Test on iOS (setting alert theme is only supported on this platform).
Prior to testing, make sure what theme you have set on iOS device. Then set app theme opposite to theme set on device. This will make sure, that Alerts use app theme rather than system theme.
Testing each location where the Alert import was replaced can be time-intensive, therefore only selected areas have been inspected to determine if the Alert function operates as expected:
- Login panel -> invalid username, empty password
- Edit message -> cancel editing
- Edit password -> not matching passwords, incorrect pasword
- Logout -> keep login info in chain alert
- Delete account panel -> invalid password
- Chat -> leave chat
