Passkeys not working on PayPal, Keycloak, and Ebay

As with others, same predicament.

Chrome Desktop gives A passkey can’t be created on this device or browser. To see what’s supported, visit our FAQ.. Alright, paypal won't support desktop browsers, I'll try my mobile devices...

Tried on my android with Chrome, and as above, passkey gets created but is stored in my Google account, not intercepted by 1Password. Maybe we'll have better luck on an Apple device....

Tried on my iPad (running iPadOS17), and using either Safari or Chrome (both of which paypal say are supported...) I get the same error as Chrome on desktop. PayPal doesn't like that either...

Edit 1: There is a bit of a hackey way around it. You can set your desktop browser's useragent to an iOS device and you can set the passkey (and save it in 1password) that way. However paypal doesn't seem to support passkey logins on desktop at the moment (even with the useragent set to iOS).

Edit 2: Trying to login to an iOS device using the passkey added via the above method, paypal (or the iPad? can't tell) just says that there isn't any passkeys for paypal.com found in 1password.
