MIUI seems to kill the app despite disabling battery optimization about taptap HOT 4 CLOSED

Just for your information: there are some steps which could help https://dontkillmyapp.com/xiaomi, but it needs to be done manually. (But apparently disabling the battery optimization alone is not enough on MIUI...)

from taptap.

Try this:
Open the app, open the accessibility settings through the app, and enable/disable and re-enable the accessibility service. Then restart the phone. If it still doesn't work, then open and close the app, go to accessibility settings, and enable/disable and re-enable the accessibility service. I'm assuming you've disabled battery optimization, locked the app in recents, enabled autostart, and set the battery saver to no restrictions

Please try with the new update, specifically trying one or both of the new advanced options.

Seems much more stable now
