Apps wont download after update OS 11.

Hello,

After updating to OS 11 on phone, apps wont download.

App store asks for APPLE ID over and over and says DONE with a bell, but nothing downloads.

I am reading many others are having this same problem. Any solutions that work?

I have tried hard reset, login with Icloud, log out. Log in etc. closing apps .

It is costing us money not to be able to use this expensive phone when it has bugs like this.

Any solutions that work? 😕
