So I have a mouse with 2 thumb buttons, I've created custom keybinds profiles for some agents and I always use the first thumb button for moves like Neon's relay bolt, Killjoy's turret, Reyna's devourer or Chamber's rendezvous and it is with the latter that I have a problem.
Basically I use the first thumb button to use the rendezvous it's great because I can tp pretty easily and quickly, while in training mode it works perfectly but once I get into a real match in any mode it doesn't work. I doesn't do anything, like I didn't set the key binding, but I check the bindings mid-game and there it is, it just doesn't work.
The same button works perfectly with any other agent, the problem is only with Chamber's abilities, mouse button 2 works but it's not that close and kinda uncomfortable and I already made sure there is no conflict or anything and I use a red dragon mouse that didn't required me to install drivers or anything.
