Previous issues resolved, however I am now experiencing a situation where Cardiogram is not updating for many hours (12 hours currently). I have forced a resync, force-quit the app, cleared the cache, and restarted my phone to no avail. The app associated with my watch is up-to-date and showing me real-time info, Cardiogram just doesn't seem to be updating.

I like the app and recording functions, which will help when talking to my Dr. it was working great on my Samsung S24 till last week 9-4 then I started having issues with it opening, it will freeze and give a message it can't be opened and to restart the app. I have to shutdown and restart the phone for it to open. it usually happens the 1st time I open it for the day, but has happened more then once a day. UPDATE after deleting and reinstalling it's working perfect now. Thanks!

I was using this on the 30 day free trial absolutely perfectly and I would of given it 5 stars, however, since im now on the free version I cant even open it without it crashing and shutting down. I cant even subscribe if I wanted to as I have zero access to the app. this could have been a coincidence or since the update šŸ¤”
