Anyone else experience this bug that secondary button isn't working?

I have my ads and secondary on the same spot, above or underneath ,and the only problem i used to face with, is a small delay until it actually register the utility or the bunker/bubbles that I throw ( although I assume its because I kept my joystick forward which leads to the character to keep moving).

Now for some reason all of a sudden it stoped working at all and it doesn't throw the item no matter if I try to aim it's just shows me that the character is trying to throw it but it won't throw it.

In addition just curious dose anyone else experience a bug that the game sometimes turns on your auto fire even if it's off?
