Uploaded on Aug. 24, the “major backend” update for MTG Arena did not go as smoothly as Wizards of the Coast had hoped. The patch was initially scheduled to take place on Aug. 10 but moved to Aug. 24, providing the MTGA team with additional time to work out kinks. Resolution towards solving these issues began today with a fix to the “error uploading data” message players received upon logging into MTG Arena.

We have addressed an issue for those experiencing “Error Uploading Data” screens when attempting to login to @MTG_Arena.

This error can be fixed by fully relaunching your game client.
