Worked for a few weeks and now won’t sync – Sync Solver - Health to Fitbit Review

Won’t sync, there’s clearly a bug when you go advanced to sync back. The screen is black and you can’t see the numbers to change the date to sync to that date. But regardless of that issue, it’s just not working at all. I’ve deleted it and re downloaded it, revoked Fitbit access and re synced and it still will not sync. I sent a message through Facebook which seems to be the only way to message anyone (or Twitter), but there has been no response since January 2020. This app gets one star only because it did work initially and I cannot give it 0 stars.
