Contacts disappeared

[Circles]

Hello,

I installed AquaMail today to try it out.
Later I noticed all my contacts had disappeared from the "contacts" app, except for 3.

I am not certain the 2 events are linked, but I have done nothing else of importance to my phone today ...

Any hints how I can get my contacts back? I would be most grateful ...

What / who synced the contacts that disappeared?

Are they your Google contacts? Corporate Exchange contacts?

Did you remove an account (managed by another mail app) when you installed Aqua?

Aqua Mail does not contain code to mass delete "other apps'" contacts. But it's conceivable that maybe you deleted your Gmail account from the phone's Settings and that removed your Google-synced contacts?
