Mind sharing which U2F dongle and phone you use?

I haven't been able to get any Google Titan Key to work with any Apple device via NFC.

I have a Yubikey 5, Yubikey 4, and a Feitian Bluetooth key, the Feitian is basically the unbranded Google Titan Bluetooth key. Both work fine, although I haven't used the Bluetooth one in a while. I use my Yubikey 5 on a regular basis.

I use an iPhone 8.
