Twitter on safari no remember me option.

I have safari 4.1.2

Big Sur 11.5.2

I have more than one twitter account.

When I went to the login page on twitter is gave me a list of my accounts to log in as.

I don't get this any longer.

It just asks me to enter my @ name and password.

I have my accounts in my keychains.

This did work a little while ago but has now stopped.

The strange thing is... if I go to https://twitter.com/i/directory/profiles and use the login option top right it comes up as it used to do.

It works fine on Firefox..it used to on safari until a little while ago.

Any Ideas?

New look login option no remember me function screen capture.

Old type login which does give me a full list of my accounts.

In my keychains I have my accounts listed in both options twitter.com and Mobile twitter.com
