Unable to add Tester Email Address to Google Play Console

Question

I am unable to add new Testers Email, in Google play Console. In my Application , I have a list called Beta Review Team ,Under that I have a list of emails for test users. It has worked for the past few years. I have Currently 84 testers. (Find screenshot 2)

I need to add one new email to this list. Is there any limitations for test users? Can anyone please help me?

Answer 1

Press ENTER after you filled the emails to the textbox. I discovered it after I got emotional ("do you want an Enter little **** or what?")

Answer 2

I was getting an error ("This email address doesn't exist") when trying to add a new email to my email list.

I figured out that I can only add as tester an email that was previously added to my Google Developer account under "Users and permissions". So after I added that email there and the person accepts the invitation to join my account, then I was able to add it with success to my test email list.
