Yes. It was. I unblocked me yesterday. Fortunately, I have never been blocked from playing the game.
The companion app has become super aggressive. I don't know if you guys updated the software. All the recent reviews of the App on the Apple App Store are negative and other users are experiencing the same issue, that are not breaking rules. More than half of the reviews for the app are 1 star. Apparently, even if you answer the authentication correctly, only sell items in your binder and acquire items for sets, it will still block you.
EA released a lot of cool new content on Madden, Ultimate Team Masters, Calvin Johnson 99 UL and Ed Reed 99 UL, so it should recognize that there would be an uptick in use of their software, rather than penalizing users from using the software and tools it offers. EA should consider that the Madden 21 Team Master and Team Builder sets require a lot of items to complete, which requires active bidding and selling. Part of the fun of Madden has been searching the market place to get the most of the coins you acquire from playing the game and building the super "ULTIMATE" team. Opening packs, collecting cards and using the auction is supposed part of the fun.
At this point, I won't be surprised if it blocks me again. I understand that security needs to be in place. Bots cannot be allowed and people shouldn't have "farm accounts" and be paying for coins for 3rd parties. However, this update to the "security", which is really poor programing and a bug, is now disruptive to regular users. The solution should not be more disruptive to the problem. I hope this feedback is useful to EA. I understand that you may not have control over the Apps security, but maybe you can relay the message to the team that does, that it is now taking away from the user experience and from the fun.
