Hello,
I play on an HP laptop, which I believe counts as a PC. Yes, I was able to get rid of the ad only by restarting my computer, and may I say how extremely disruptive that was. (By the way, closing the EA app also did not get rid of the ad, which I forgot to mention before). I had to close the game, close all the programs and applications that I was using to do some work, etc. It was very inconvenient. When the computer finished restarting, the ad was gone from my computer screen, and when I eventually got around to restarting the game, the ad was also gone from it. However, having to do all this was annoying and I certainly don't want to have to shut everything down, exit the game, and so on, every time a pop-up ad appears (especially as I already own all the packs and kits, except for Journey to Batuu, which I wouldn't take for free). So I really hope that EA fixes this problem, or, better yet, gets rid of pop-up ads altogether.
