Try using a site like time.is to check how far off. TOTP codes are based on the current time rounded to the nearest 30 second interval, i believe, so more than that may cause issues. Typically servers accept codes that are off by one interval though
do you have any links/more info about the people who had issues running their own infrastructure? ive been following Signal development pretty closely and all features im aware of make sense that they would not require a server code change. I’d love to see any actual technical details over the hysteria in this thread.
Recently started using FitoTrack. It doesnt do everything MyFitnessPal does but it does what I need
