That is in fact something I’ve been debugging! The update may actually fix some instances where that was happening. If you’ve noticed any specific circumstances where it stops syncing, could you add details here or email support with them? It’ll help a ton.
Right now the workaround I’ve found works is to go into the app (often this alone will fix the issue) and tapping Reset Data in the settings screen - if you’ve found that this doesn’t fix the issue, there might be something else going wrong.
