Same for me, in Windows version... After playing some matches without error.

And delete that file doesn't work

Following the comment by https://feedback.wizards.com/users/5500850649--iln-1-80024 worked for me. The actual file(s) to delete are:

%MTGA_Install_Dir%\MTGA_Data\Downloads\Manifest_*.mtga

e.g.

C:\Program Files\Wizards of the Coast\MTGA\MTGA_Data\Downloads\Manifest_39841652dc16278da5893053aa6d484d.mtga

Also having this problem constantly

This happened on my IPad Pro. I changed the setting of save downloads to the cloud drive to save downloads to the computer (IPad), and I was then able to finish and complete the download

On PC, deleting the old downloads.manifest file worked.

Make sure you've updated your Android Game Client on the App Store to
Version 2021.4.10.662

Check the comments below to make sure you're not running in the IPv4/IPv6 issue mentioned. I detail some steps on how to test this.

Same issues. Anyone able to successfully navigate this on their phone?

I still have the problem and it would be great if it finally worked

I have the same problem: Error updating Data: pleased Check your connection and try again.
and that for almost 2 weeks. Only retry Button

have a Lenovo IdealPad duet Chromebook.

Mtga Version : 2021.3.22.609 and load with Google App store.

I had to install it several times and it still doesn't work. Everything works fine on the pc, but I could play more often on the chromebook. Please fix and report. Many Thanks

This has been an issue for so long.

WoTC sucks ******* **** ******** Hasbro.

I've got to assume it's an incompatibility thing but, I would report it because I hear you. It's why I play on PC anytime I can. It's just a better experience but, being able to do it on the phone for a quick game/s on the go, awesome

@HeyBuferd

Yes, on my Pixel 5 the app works just great. But for sure not as awesome as it could be on a convertible chromebook.

@schatten#04209

Ok, just wanted to make sure it wasn't a IPV4/IPV6 negotiation issue.

Thanks for the info on no side load either. I know there is a page somewhere in the forums that seemed where people were reporting their devices that won't work. I think I remember seeing it under "mobile" and it was a highly voted one too.

By chance, have you had it work on an Android phone?

@HeyBuferd

Thanks for you comment. Now I just installed the warp app from the PlayStore and setup VPN. Still the same problem. It also doesn't matter if I use my wifi at home or using a hot spot from my mobile phone. Any other advices to solve the problem? I didn't sideloaded the app on my chromebook, it just shows up at the store. My old chromebook for example didn't showed it up at the store.
Did someone of the developers take notice of this problem on chromebooks?

@schatten#04209

Try seeing if you can use a VPN by chance like I mentioned below. I assume there might be something with it being a Chromebook and just not supported yet. However, your Play Store should have filtered it if it wasn't compatible.

Try the VPN route and report back if that works

I have excactly the same problem. I got my new chromebook today and installed MGT through the PlayStore. When I start the game it stucks while starting and I get the same error. My wifi is fine and is just working. I really would love to play MGT on my chromebook. Convertible and touch screen is the perfect setup for MGT.

After further digging, it appears this could be a problem with T-Mobile and Sprint APN's only using IPv6 by default. Changing your mobile APN to allow IPv4/IPv6, allows the game to work as well. You can also use a VPN service like WARP from Cloudflare to workaround the issue.

Seems this is an issue with T-Mobile and Sprint carriers...
