Bug Report: Cannot Save Garmin Coach Running Plan Updates

Cannot save any updates to my Garmin Coach Plan within the app. See attached video.

There are two separate issues:
1) no changes to the plan can be saved; stuck in infinite retry loop with "Something went wrong."
2) long run days cannot be updated if the Training Days are not selected first. Must close and reopen app.

These issues prevent me from adjusting the Running Coach at all!
