Re: can't access companion
The companion app doesn't exist anymore.
Even tho it should be still acceptable vie a web browser here: https://companion.battlefield.com/companion/login
And the regular Battlelog for BF4 here: https://battlelog.battlefield.com/bf4/gate/
But as i noticed the games that show up within the companion app (BF1,BF4) show just "get now" in the career as if you wouldn't own it. Probably as the app isn't supported anymore.
You still can click through the tabs like platoons, emblems and friends.
So maybe it let's you still edit or change your emblem, not sure. Give it a try but don't expect too much.
Via Battlelog you should still be able to change or edit the ones which you have there, not sure tho if those will also transfer over to the ones which will be available for you in BF1 then.
I just tried to create another one via Battlelog and it did not move me over to the companion app. Worked fine for me.
