When trying to update apps I had previously installed I get the message "Account not in this store", saying I must leave the US store.
My region is UK and I have Apple iD and valid payment for UK.
How do I change back to the UK store?
I even tried creating a new Apple iD and still have the same issue.

Then click on your name/email at the top.
Then you should be able to change your AppStore/check your country or region there:
