Export from iOS app

I am trying to export my 1Password data to Bitwarden on my iPhone. I have active subscriptions to both right now and want to use Bitwarden as a backup.  I got into the iOS app, choose Export, type in my account name. I select Bitwarden as my destination, click Continue and it just sits there and does nothing.

I tried a second time to export and chose thr Passwords app and it also just hangs there.

Eventually the phone locks and when I unlock it, it tells me the export failed.

What am I doing wrong here?
