Taking screenshots isn't allowed by the app after ...
Try the Tesco Clubcard app. On taking a screenshot you will get a toast saying: "Can't take screenshot due to security policy".
This is what I'm referring to in my post above.

Like "disable right click" on websites I really struggle to see how this is useful to Tesco in any way. It's trivial to bypass.
What's their threat model here?

I don't know about Tesco but I believe it's common on bank apps to prevent malware from screen grabbing your details when your bank app is open.

Yeah, I've seen it on other apps where the payment flow screens block screenshots for this reason.
