Unable to sign-in on iPadOs "Load Error" Chrome and Safari

[xlfe]

I'm seeing a weird issue where at the last stage of the loading I get an error that just says "Load Error".

This only happens on iPadOS (both safari and chrome).

I've just updated to use the latest AuthUI container and I'm still getting the error.

I don't have a Mac so I'm not sure how I can debug it further. Is there something I could do to expose the actual error message without needing access to the Dev Console in Safair or Chome on the iPad?

I have no problems signing in using Chrome on Linux and ChromeOS.

I get the same error whether I'm using a Google account to login or a Username/Password

I have just discovered the issue does not occur on another iPad, so I'm not sure what's going on, but I'll have to do some further debugging. Sorry!
