Crescent Edge not work properly (no regain ap)

Yep, it dosnt work properly, sometimes it dosnt trigger 2nd attack after first kill.

It happened with glenn, who has follow through. I think, if ft dosnt kill the 2nd target, it stops the 2nd attack. I hope, you understand, what i mean. Even if 1st attack kills the enemy, but ft dosnt kill, it stops the 2nd attack.

Trust me, it was the first action. I was standing there because of walker mike.

Wish I could. The help button doesn't work for me...

what about press and holding 3 fingers on the screen?

That worked.

The game play is so choppy now, it's really easy to make a mistake while trying to move. 

Copying my response from another thread, for your visibility: 
We are investigating the the FPS drops at the moment, along with a few others.
Some of these issues seem to happen to groups of players, rather than being widespread, so we have also not been able to consistently reproduce these on our end. Please do submit support tickets for these if you haven't already, the queues are quite long right now and responses will take time, but the reports do help us investigate the issues. 

Our apologies to those experiencing issues from the update, we will do our best to get these resolved as soon as we can.

There are other issues too, tried to play a scavenge mission ( tomato 🍅 Monday) , got a weird screen, froze and two days since, I'm unable to log in...

I am facing the frame lagging issue in the Distance. Other modes (daily missions and Last Stand) are working fine. Lets hope there are no frame lagging issues in the Weekly Challenge.

I am facing issues with Tactical. I had tactical on all my survivors in Last Stand. Most of the times tactical did not activate and they went into struggle, resulting in me achieving 50% scores. Prior to the mini update, Tactical was working fine for me.
