Not an expert here at all but are you sure they’re not complaining because you haven’t implemented FB login? I know you don’t want to use it but given past experience here I imagine they very much want you to use it.

“Didn’t integrate it at all” does fall under “failed to properly integrate” after all.

It's possible! Hadn't thought of that. What's most frustrating is that they don't even tell us that. If they did, maybe I would integrate it. But without being sure, it could be a massive waste of time.
