@EA_David unfortunately issue is still persisting on my end, it seems like its really only occurring to players who've taken rather large/long breaks 1-2 years
Still persisting on my end as well.
I've had a support ticket open and initially got the connectivity troubleshooting, when I ensured them it wasn't a connectivity issue on my end, the next agent asked for account details to fix the issue, however when I replied with the account details, I got a response from another agent giving me the same Microsoft article linked previously here
I pushed back on this so hoping eventually it gets to the right agent that can fix it. I've also linked to this thread in the support ticket to raise more awareness it's not a one-off case.
@EA_David I'm definitely still getting the error: detected data mismatch. For additional context, my account has had this issue since S16 release; it somehow has two separate content profiles linked to my account...one with all my battlepass skins / legends / heirlooms and another that didn't even have legends unlocked on it, but the account level and stats are the same and I was still able to play the game. Now with S17, instead of being able to play on this "second" content profile, I am presented with this error and unable to play at all.
This is pretty frustrating
