Just did a multicam of a wedding. 2 cameras moving back and forth from the groom to the bride as they said their vows. The rapid change of angle looked jerky so I wanted to add transitions. Since it was multicam the audio had its own track.
After adding transitions I discovered the audio was now out of sync. I think each transition added length to the video timeline making the audio get worse after each transition.
Is there a fix for this?

Have not used multicam. Have you considered removing the transitions and the splitting the audio (double click clip or project > split audio) which will put the separated audio on its own track. Then you can alter the lengths of the clip/project and transitions and see if you can get the result you want by adding audio.Never tried this but it is all I can think of

I've seen that before and as a wedding filmmaker I solved that issue by using an overlay transition OVER these two clips instead. Nice and smooth!...

When we apply a transition the two clips shuffle together / overlap by the duration of the transition.
This causes all clips to the right to move left and yes will affect the other tracks, your audio going out of sync.
The content of the video during the transition may affect how you do this.
1 / The overlay option mentioned may work but I suspect the end of transition may not be as smooth as we would like, no harm in trying, it really depends on the video content at that point.
2 / We can apply transitions to the end of our clips rather than over two. Use the scissors to cut the clip, then apply the transitions, a slightly different effect but will retain the audio sync, fade-out then fade-in, I would have thought a crossfade may be as good as any.
3 / the program has a Multi Cam Editor i see you have used that, it does / can also add transitions which would retain audio sync,
4 / you could render the project to a new video file, using that file cut the clip to apply a transition,
Although that would retain the audio, but affect the audio during the transition, you may need to manage the audio fade in / out during the transition.
Then render again.

Actually, each transition REDUCES the length of the video timeline since formerly separate clips are now overlapping, but indeed the effect is to make the audio go out of sync if it had been previously in sync but on a separate track.
I am assuming that the audio truly comes from a separate source (e.g., a lapel microphone worn by the groom) and hence must be on a separate audio track. (If you split it off at the start from one of the video tracks, that was possibly counterproductive--I would do all the multicamera and clip editing first and then if you really need to split off the audio for further processing, do it at the end when the times of each clips have been fixed.)
If you had all your clips manually interleaved on one video track and somehow all synced to the separate audio track (not sure how you would have even done that, other than very painstakingly!), and are now trying to fine-tune between the two cameras, that's the hard way to do multi-camera editing!
Probably the easiest way to do this, especially since you have only 2 cameras and don't even need to bother with the multicamera feature, is to choose the primary track (or the one that overlaps the most with the audio and put it on the main video track). The 2nd camera's video would be on an overlay track (the overlap appears smaller as a picture-in-picture effect by default, but it's a simple matter to make it full size), and the audio track is separate (and the audio from both video tracks presumably muted). Assuming you start out with everything in audio sync, just delete the parts of the overlap track where you want to the main track to take precedence. And the overlay track will take precedence over the main track wherever it has not been deleted. Then put all your cross-fade transitions on the edges of the clips on the overlay track. This works since a clip on the overlay track always stays put, regardless of whether you cut sections off to either side of it, or apply transitions. This is NOT true of the main track where any deletion or shortening of a clip (including that caused by applying transitions) will make everything to the right shift left to fill in the gap.
Now if you also want to cut out parts of the main video track (groom fumbling with the ring ...) and make sure the overlay and audio are cut along with it at just the right parts, you can do this with ripple editing, making sure your cuts are being applied uniformly to all tracks (main, overlay, audio).
