It is possible. It seems to be a polling issue, so some logic that worked before could’ve been broken by the android update.

I updated android itself about a week before updating warp-app. Within that week, warp-app was working with DNS-over-WARP. After the warp-app update, it broke.

I do not know if this is because the old warp-app was hanging on to older versions of dependencies. I am not familiar with how android handles them.
