- Clear pw forums app data & cache.
- Uninstall app.
- Turn off phone and take out its battery for a minute.
- Reinstall app.
- Open app with wifi off and mobile data (2G or 3G) on and login.
Note: Reinstalling app and clearing data & cache are two different things.
I tested this app on S5 and note 3, but not on note 4. It works for me.
You can also try installing its previous version of pw forums till the bugs get fixed.
