nextclou 22.0 Use talk11.2 Android version to connect to the server, prompting that the talk application is not installed, the actual server has already installed the talk application
Unfortunately yozr posting is missing DETAILED information about your environment, used php and software versions and how you’re EXACTLY trying to connect to the server, e.g. if you’re on your LAN, on the internet, if a firewall or a proxy is used, etc., etc.
since update in OS ubuntu 20.4.3 to nextcloud 22.2.0, nextcloudTalkAPP 11.1.2 doesnt work any more
