Unable to sign in to Feedback Assistant.

Still present on Feedback Assistant 5.1 (487.2) on macOS Monterey 12.3.1 (21E258). Anytime I attempt to login, I'm greeted with the following message:

Unable to sign in to Feedback Assistant

Thank you for your patience. Please try again later.

I haven't been able to login to Feedback Assistant for at least the last 9 months, but only just found this thread. 😅

Cannot sign in, Monterey 12.4 (21F79)

Unable to sign in to Feedback Assistant Thank you for your patience. Please try again later.

What is causing this?

The issue persists on Sonoma 14.4 - every time the user signs in to Feedback Assistant, the app insists it does not recognise the (guaranteed correct) password, and insists on a reset. User resets the password, then attempts to log in once more to Feedback Assistant - same deal, FA does not recognise pwd, and insists on a reset.

Repeated the procedure four days in a row - same result.

Is there any way to delete this pointless brick of an application?

Worse still, it insists you change your iCloud password, which it does successfully, but then tells you, when you try to log in to Feedback Assistant again, that the newly-minted password is 'not recognised' - so you are stuck in a loop of infinitely until Doomsday, of changing your one sacrosanct password time and time again, until at least you have proved to yourself, experimentally, that Feedback Assistant is Totally Broken!

This is annoying for sure. Its happened multiple times in the past but resolved itself eventually. But as of two months ago this happened to me and I was locked from my phone and my account. And now again. I just want to report some issues I’m having since the recent beta update. But nooooooo I can’t. Ive attempted to sign into my account via iPad, iPhone, MacBook….. I’ve attempted to change the passwor. Last time this happened I called support and it took us two hours to figure it out. And unfortunately i dont remember what we did to get around it all. frustrating to say the least. The loop like the last person said above me is totally where this is happenin.
