I implemented 3 attempts with 100ms before each, so that on most devices, it will work within 100ms (so the popup is not visible for too long), but on others it will still work: bc82e34

Here is a full build for win64:

Please tell me if it works for you.

Yep. Working on my phone. Thanks. I think we’ll wait for feedback from other users, and close this issue

After 5 hours of misunderstandings with Linux I finally installed it. Delay of 300 (units, seconds, whatever) is working

Yes, I noticed that yesterday 👍 It will be fixed by aa6846c (not merged yet).

I just saw all these branches. What a horror)

Alright, with a delay of 250 it seems to work fine every time. I haven’t tried any other values, though, but I might later.

EDIT: After a bunch of restarts I did manage to get it to fail. 300 might be better then.

Are you comfortable to build the app from sources? You could try to adjust the delay until you get a value which works for your device. I’m interested in that value 😃

It doesn’t look hard, I’m going to try it now
