App keeps opening in system browser

**Describe the bug**

I received the following review on Google Play:


The user reports that the device always opens the app in Flyme browser, which apparently is the system default browser (and cannot be deleted), even though he has set Opera as the default browser, which should be PWA compatible?

**To Reproduce**

Can not reproduce. Other users with the same Android- and app version seem to have no problems.

**Expected behavior**

If the app says that it is available for the device in the PlayStore, it should always work as native experience.

**Smartphone**
- Device: Meizu M5
- System default browser: Flyme v 8.5.110-2021020110
- User default browser: Opera (unknown version)
