iPad Sign-in Required

[Gusz]

I have an iPad Pro 2017 running ios 11 public beta 7 and I keep getting a "Sign-in Required" pop-up requesting my password. I'm wary of such pop-ups being malware password traps, and the pop-up doesn't identify who is asking for my password.

How do I get rid of the pop-ups? If this has to do with iCloud (or Siri), I don't use them and have tried to disable them (unsuccessfully?)

When I’ve had these pop ups, they’ve been from the App Store. My main account is a British one, but I also have an American account, and when an American App needs updating I get this popup.

The same thing is happening on my iPhone! I only have one Apple account. It's extremely annoying.
