Doesn’t sync automatically – Sync Solver - Fitbit to Health Review

I have this app for months now and it doesn’t do what it claims. It says “ it may be necessary to manually sync from time to time in order to keep Sync Solver automatically syncing on a consistent basis” but unless I manually sync, it doesn’t sync at all. I tried multiple suggestions found in reviews here and the developer support website but nothing really works.
