Ours was very strange, it was an out-of-review decision at the height of our popularity and said our app would be removed in 14 days if it wasn’t removed. They scheduled a call with me to explain their decision only after jack @‘d tim apple.
When I talked to miljan they said their only issue with apple was NWC, but my reviewer didn’t care about that at all, the only thing they had issue with was zap button on notes, but that doesn’t even violate any guideline as I read it because we’re not using it to sell digital content.
Basically they can threaten to remove you for any reason, they don’t apply their guidelines evenly, and they hate threats to their revenue model.
