I expect that after accepting the prompt and giving it permission to be my default message app, it should be so unless I deactivate it manually and I should have the option of using my other apps normally if need be.
Actual behavior
After accepting the prompt and giving it permission, it resets whenever I open my normal SMS app.
How to reproduce
Install QKSMS app
Open and accept prompt
Grant it permission to be your default message app
Now, open your normal message app
Go back and open QKSMS app, it'll now reason for you to set as default message app.
