[me.bluemail.mail] can't add Gmail account

[Black_Eyes]

Affected app
Name: BlueMail
Package id: me.bluemail.mail

Describe the bug
When adding Google account to BlueMail, I think it is supposed to show a Google loging screen, because it kinda tries to redirect to a new screen, but immediately go back to BlueMail without showing anything

To Reproduce
Steps to reproduce the behavior:

1. Go to BlueMail
2. If it's not installed, try to add a Google account during initial setup, else, try to add one using the three dots, bottom left
3. Type your gmail adress. Bluemail will try to force you into a Google screen connexion but will fail.

Expected behavior
I don't remember how it works on a normal phone, but it used to work on my stock rom with normal Google play services
Currently using lineageOs

Screenshots
I can take a video if you want? A screen shot won't help
