Adobe Animate Auto Lip Sync Lagging

[TravisBCP]

Hi,  I'm using Animate to auto lip sync my characters, and it works great, but begins to lag after about 15 seconds.  My animations range between 2 and 5 minutes and the auto lip sync ends up being very far off the mark by the end.  Does anyone else have this issue or a solution to this problem?  

Currently, I take the mouth into after effects and fix the lag manually but it would save lots of time if I could find a better solution.

Thanks!

make sure you have the latest version of Adobe Animate version 20.0.3.

Thanks for the reply.  I do have the latest version and unfortunately the problem still persists.  Here is an image of the problem:
