Passwords Add.on KIWI Browser fails

Installing the browser add-on with Kiwi-Browser is no problem. But it does not fill any fields.

With newest browser and android-version (12) I get the old-hand message:
“Could not establish connection. Receiving end does not exist”

The old thread from 2019 doesn’t help because the mentioned options don’t exist in new NC (24.02). And the hint on the passwords-wiki concerning Kiwi-Browser doesn’t equally exist in modern kiwi://flags.

What can I do?

Sounds like a problem unrelated to Nextcloud. Did you ask kiwi maintainers?

Same her … “Could not establish connection. Receiving end does not exist.”. After 3 hours of testing, reinstall … sometimes it works, sometimes not. All after update NC to 24.03/4 and 2.2.4.4461 on Chrome.
