I play on an android phone and after the Khans update, I get the same message when I attempt to log in. I have Uninstalled and reinstalled the launcher, attempted to download over wifi.

after updating to the newest version of game, i find out that i cannot login to the main interface of the game, please give me some help

Error updating data
Only happened to me after the khans update

Been following this, I can confirm I also have a brawl deck with - viconia nightsingers disciple commander which specializes.

someone publish on twitter that the problem persist if you got some deck specialized. I dont know if that is true but i have got some deck with specialized commander and after patch i cant login. Someone comment with new account can play. Some one here got some specialized commander deck to check the trust if is probably the error?

Hopefully this issue gets patched soon. Was excited about Khans, now kinda irked about losing 3 days of dailies.

IOS.
Cannot open or load game since last update. Open app, attempts to load, and error updating data: please check your connection and try again, and again, and again, and again. Will not pass this error at all.

I have the same problem since the update

If you need more confirmation, I have a boros Lae'zel HB deck

Maybe you guys could just get rid of 'specialize' and instead give us the Background enchantment cards? Eh? Eh?

Did you all try downloading the update like the SECOND it was available? I am just speculating that somehow a small group of us were so eager to play that we downloaded a faulty update that was quickly patched but not before sending those few of us into this weird update limbo

I want to play Historic Brawl, but I can't due to an error...

Apparently this is affecting users who had an Historic Brawl deck with a commander that has a specialize ability.

If you are right, I can confirm I had a brawl deck with Lukamina commander with specialized ability

I cannot login, past 3 days, changed internet, changed pc.. i think it's related to our account..

Unable to login. Error updating data code. Been 2 days. Please fix.

Why is this still a problem. Can't log in since patch. Are you going to issue an update or what?

I am somewhat of a deck hoarder and have like 97 decks, so it pinged me for that one possibly. I know I build one but im not sure I still saved it because i hastily put it together

Is this true, that it's affecting users who had Historic Brawl deck with a specialize commander? That would explain my issues.

Can not launch since last Update on 12.12.
See attached Errormessage.

I am having the same problem still. I've uninstalled like 4 times now, even tried installing the Steam version. It looks as though this is server side.
