I know this has been posted about before, but I didn't see any solutions for the current version and didn't want to necropost.
Settings > Sync > Account > Login, use the credentials that work on mailwasher.firetrust.com, and I just get the spinner for a second then nothing else happens.

Is there anything that can be done about this, or do I have to wait and hope they finally fix it in the next version, whenever that is?
Thanks.
