Dave,
I just tried again and the error message says you already have an account under public -at-hpeer.com and I need to use a different email.

I believe I have done that in the past using howardpeer-at-gmail.com.

That does not work either I think.

HPeer...
On Android Forum, we only see an "hpeer678", last seen on the forum in 2022.
Is this you?
We see no other "hpeer" at all.
Please try again, maybe hpeer02, and we will watch carefully.
Thanks
Dave
