Form filling works only after 8 tries (Firefox + Android)

[chross]

I'm using a POCO F2 Pro with Enpass 6.7.1.572 and Firefox 94.0.0-beta.2.

When I try to fill a form, the "Enpass overlay" (Autofill with Enpass) will show but almost instantly vanish again unless.... I try to fill the field about 8 times (I switch between username and password fields), sometimes more. Then, the overlay becomes permanent and I can click it. Here is a video:

I have attached screenshots of my settings, they are in German but basically, enpass is set as an accessibility service, is activated and registered for autofill.

 

Any suggestions for this annoying problem?
