Apps can't be locked to recent apps list in MIUI 12.5
The Redmi Note 7 received an update from MIUI 12.0.1 to 12.5.1, and now the instructions for locking an app to the recent apps list no longer work. In MIUI 12.0, long-pressing an app in the recent apps list showed a set of actions, including a lock/unlock action. In MIUI 12.5, long-pressing shows the app info screen instead.
This means we don't have a way of protecting Briar against Xiaomi/Redmi's power management on MIUI 12.5, and the instructions we're showing during account creation can't be followed.
