The new mobile app sends notifications for each track change, as if the “Send Notifications” setting under “Desktop Integration” is on by default, which obviously doesn’t make sense, given this is the mobile app. The aforementioned likely is the issue, as I found the Linux Flatpak does indeed have it on by default, and if all the apps share the same/similar codebase, that would make sense.
The notification only appears for a second (my watch notifies me when it appears), so the above screenshot is from my notification history
