I too recently reinstalled the app.
No, i haven’t used it at all and miss my emblem too.
edit: I was of course talking about the companion app.
I did. but it did not work.
Don’t use it and have the issue as does everyone that plays on our server.
hmmm so it’s not just people who’ve used web companion then. Well seems like EA/DICE broke BF4 in game code to do with emblems whilst trying to implement compatibility for web companion but broke compatibility with battlelog emblems at the same time… 
Only consolation is it’s not an issue to fix on our end. :* The thing is all we can do now is report the bug and wait until EA/DICE get their act together to fix it… Who knows how long that would be since it’s not game breaking (so probably low priority…) but annoying all the same. 
It seems that you need to remove the emblem you are using on the Battlefield 4 site.
Create a new emblem with something in it and then “use” and then remove the emblem without “using” any other emblem.
Go to the Battlefield Companion and finally equip your emblem. You join the game and you should see the emblems.
I have no idea why it works, but that’s how it worked for me.
Gonna try now.

Edit: nuffin 
Did it work once (one round) ?
Try joining the CHE GUEVARA server. It works fine for me there (Hardcore TDM server)
No, still didn’t show it.
.
Will test it on that server tonight.
Please do because it seems to be everyone having the issue, so it has to be something on EA/DICE side. Maybe during the XP weekend setup or BF1 Companion crap App did this…
Emblems were back on our server today.
Yesterday evening my emblem was back. Now it is gone again
Try joining this server : http://battlelog.battlefield.com/bf4/servers/show/pc/ccd13151-7e37-4c6c-88f6-e98b7c2611a2/1CHE-Russian-hardcore/
(requires PREMIUM)
It works for me there.
It’s not really fixed if it only works on a hand full of servers. Plus that server isn’t in my region so it’s poor ping for me if I play there.
Is it still working or have they disappeared again?
Maybe servers needs to be reset? If that doesn’t work it def needs to be fixed on EA/DICE side.
On a couple of servers they work and on the rest of my favs, they don’t. Strange…
My emblem is back now 
Played yesterday evening and this morning.
Still the same. On a couple of servers they appear, unfortunaly on most of my favs, they don’t.
yes,IT HAPPENS
Always breaking something and then acting as if nothing happen. It’s not EA/DICE concern anymore, its all about selling BFV now.
Seems to be fixed now… Most the servers I play on are now displaying custom emblems again
