Firefox Sync always used to work with the IOS browser Icab Mobile, I noticed one day - that my Bookmarks were not syncing?

more options

I have used Firefox Sync using Icab browser using the Old Firefox Sync - and then with the new Firefox Sync - everything worked Perfect! recently something must have happened, sounded like there was a hacker attack or something. I found a message on Firefox support that this issue had happened. I can Sync with computers, I can sync with the Firefox ios browser. But when I go to Sync in Icab - and log in - I get the message: "Login data is not valid. Syncing is not possible" I talked with Alexander at Icab Mobile Support - he said you were working on a fix..... Can you give me an idea as to when this will work again?
