I have the same issue. In Catalina doesn't work verifying of the app wich build for the App Store with sandbox tester account. It say "Your Apple ID or password is incorrect." But I'm sure I enter the correct credentials. And creation of the new tester account didn't help for me.
It's so pitty for us, becouse we can't normally test our app before release.
Same issue here. Did you create an issue for this in the new feedback assistant?
In my case when I try to do the testing, first it come up with a user ID, that I have deleted from the list of sandbox users. Somehow using that old user, a little more happens, because it then says that the app is damaged and must be downloaded again from the app store. So maybe this is an issue on the web part and not so much in Catalina?
I also tried to create a new user and not validate the account via the email you receive: same result.
What looks new to me is the checkmark for Apple Pay. That is always on, and cannot be turned off (so why display this; bad design). So maybe the Apple Pay people have messed things up?
I guess I could test how things work under the previous OS version, but that's a whole lot of work for something that should never break. It's a frustrating mess.
I've used a DTS incident to try and get to the bottom of my issue. No luck so far, we are still going back and forth trying different things.
I'm encountering this issue as well. Any updates?
I've been encountering this same issue. I've got the situation where I have an older test user (from a different app) showing up automaically in the credentials and whe I enter a known valid test user for this app I get the "Your Apple ID or password is incorrect." message.
That made me think that somehow the sign in was trying to reference this older app. To test this theory I created a new user on my Mac and built the app as that user. When I tried to run it, the sign in popup came up empty and when I entered the test user that I had been trying previously it worked correctly.
When I went back to my normal accont on my Mac I still got the "Your Apple ID or password is incorrect." message with those same credentials.
That makes me think that something is baked into my normal acount that is somehow directly the sign in to the wrong App Store Connect account. I image if I could find where this prefiled Apple ID is coming from I could correct the issue. Does anyone have any idea where this informaton is stored?

Might want to start by looking at the apple ID(s) tied to iCloud that reside on that mac.

No sure exactly whatyou mean by this, but both the mac account that works and the one that did not are signed into the same iCloud account. There are no other users on the mac and no other iCloud accounts in use.
> Otherwise, keychain.
Thanks ... this was my first tought too. I just looked again to be sure and there are no references to this older Sandbox test user in keychain.
Thank you for your ideas ...

...and yet, above you stated:
>I created a new user on my Mac
Looks like you may need to clear things up, and, consider starting your own, unique thread, with your questions/issues, etc.
