As of a few days ago my premium subscription switched over to free so it is displaying the ads. Any thoughts on how to revert to premium without having to pay again? I reached out to the developer but I haven’t heard back. Not sure if the app is still being supported.
VeraMate does not visit this forum very often so it may takes weeks.
Have you tried to look in the settings? Upper right gear icon. Select Diagnostics near the bottom, and you will see Restore Previous Purchases.
I seem to remember having to do that once.
