There's a strange bug: all the contacts that I've ever added from WhatsApp have disappeared without warning.
Is there somewhere I can find deleted contacts? I've tried restoring Seedvault backup from 1 to 2 weeks, but I still can't see them.
I can't see any traces of those deleted contacts on my cloud DAVx5 sync either.
If anyone has any idea what's happening, I'd be grateful for any suggestions on how to solve this.
