If I may report that small issue :
Despite using XDA adfree version of your very welcomed app, I noticed it couldn't get past the post log-in screen (got No connection / Try again - with no avail') if device is connected with ad-blocking private DNS on Android 9+) or to a router set with ad-blocking DNS.
No biggy but took quite some time to figure out the reason.
You might want to change that or add a message to let users know their ad-blocker prevents the app from going further.
After initial set up though, it's working fine with or without DNS ad-blocking.
VPN usage was not an issue for me, only DNS level ad-blocking.
(Tested with v1)
