Watch only code generation not working properly with Trezor wallet

I've imported my Trezor wallet in the mobile app and can use it with the device connected. While logged in, I can go to settings -> watch only and see the xpub and output descriptor - everything seems normal and I can copy them and generate qrcodes.

However, when I back out of the settings and go to create a new watch-only wallet, it doesn't work with either of those keys. With or without the biometric checkbox, I get an "invalid credentials" error immediately.

I was able to get an xpub key using the desktop Trezor Suite. That had a couple of confirmation steps on the hardware device when generating the key, and gave a qrcode with a working xpub that successfully imported in the Green app.
