Weekend 2 Bugs & Issues

So far I've really enjoyed this game.  I have come across some issues and bugs though.  I want to preface this by saying I have been running support all weekend.  There's something about laying down fire while reviving the squad that just gets your really immersed.  So, these bugs are mainly for the Support Class, and one visual issue:

The videos consist of the following in no particular order:

1. Smoke grenades have been very bugged all say.  I will throw one and it doesn't pop.  This has led to a lot of deaths on my end (one video showcases a smoke being thrown and my dying afterwards as it didn't pop and give me a screen)
2. The shield wall has not been deploying fir me at all today.  One video showcases me placing it, laying down fire, and then noticing it not there.  It also did take the wall out of my reserve, so I couldn't try to redeploy it.
3. A few times today I tried using the defib on downed players for it not to work.  The video shows clearly that I attempt 3 times, with once being a fully charged hit.  My squad mate was down inside his resupply pack, so that could've been the issue in this instance.
4. The screenshot is of a large red glare on a building that wasn't too bad while not ADS, but once I went to ADS my screen was white.

While I don't have any videos or screens screenshots of what I'm about to mention next, I have come across really bad matchmaking issues.  Matches will load then instantly kick me back to lobby or force close my game.  Other issued are after I'm done a match, I'll freeze at the "Match Summary" screen.  I haven't come across any queues, but lots of issues with matchmaking.

These are the issues I've come across from this weekend.  Some from last weekend still persist also.  I did see an interview stating the Shotguns have been balanced come drop, so I'm glad that is being sorted.

All in all still a really good experience.  This is Beta of course, so issues are going to happen.  Can't wait to pre-order next week, I'm looking forward to seeing if the game gets the balancing and polishing it needs!
