1Password X should definitely work on Paypal! We’re not able to reproduce any issues here so we’d like to ask you to email us all the details, that way we will be able to investigate and help you out (or fix whatever may need fixing!).
Before emailing us, please try saving a completely new login on Paypal’s website and see if it works. If it doesn’t, email us at support+extensions@1password.com and we’ll get back to you ASAP.
