Ok, lets look into the tech forums for Fifa, DAI, MEA and SWBattleFront2....
First one or two pages of each forum....and see how many posts are about Keyboard issues on them....
Fifa 16....one post, which @farshad_vcf_71 already posted in dated from around 2015 or 2016, and edited to say it started working.
Fifa 17 ....zero posts on 2 pages.
Fifa 18....one post, with no response from OP after EA community manager posted there last Wednesday.
Fifa 19.....zero posts 2 pages
MEA.....zero posts 2 pages
DAI....well that is here, and you found the post about it and the listed fix.
SWBF2...one thread, and guess what, posted fix was Teamviewer disabled, with people reporting Discord and Origin overlay also causing issues....seems mixed on which causing most issue.
So the idea that there is some MAJOR GLOBAL ISSUE is just false. There is a known issue between frostbite based games and things that put on overlays(aka outside programs interfering with the game), such as teamviewer, discord and Origin, which has already been made plain in this very thread. So if you wish to fix your issue, I suggest you spend time posting the info needed to diagnose it, but please use the correct forum. I would look very carefully into any program that hooks into the game and has an overlay that can be accessed ingame....such as discord, teamviewer, Origin, Geforce gaming evolved, steam, or any other.
