I used firefox on a number of devices. Syncing usually works between them all. I created an account on firefox for android but it's not syncing. I've disconnected and reconnected on this device and another couple of devices (firefox on linux desktops) but it's just not picking it up. I have no master passwords on either device (I have in the past). I'm on the latest firefox on all devices. Syncing is showing as completing successfully. I've removed all synced devices from my account except those i'm interested in.

Any suggestions?
