This hot mess is clearly barely functional. I have to reboot my device and/or logout/login again on a daily basis. There's no way you even bothered to test this before rolling it out. Why not rollback until you get this sorted out? It's been weeks and you've done nothing.
Sorry to hear you are experiencing issues with the new Pik upgrade.
If reinstalling the app/ rebooting the device doesn't help, we recommend calling our technical support for further troubleshooting.
