Does the new ctap proxy not work with disposables?

I’ve been using disposables for mostly everything since I started using Qubes. If I don’t need to save local data, I use a disposable. It’s worked great so-far.

But with the new ctap proxy, I can’t seem to get it to work that way anymore because I can’t get that disposable permission to access keys it hasn’t signed.

Is there a work around or can I not do it this way anymore?

I still haven’t found a solution to this issue. Any advice?

I don’t know how it works and I can’t test u2f but you can check the dom0 logs to see if there are any denied qrexec requests related to this and maybe fix the qrexec policy.
