Hello,
On Nintendo Switch, when you start a rift (Nephalem or Greater), any ability assigned to the “Y-Button” doesn’t seem to respond for about 5 seconds.
This can be a problem when there are many mobs right in front of the rift entrance (leading to a chain of deaths and respawns).
I have found this issue despite switching controllers, switching consoles (we have 2 Switches), and for any character class.
I have noticed this bug for a while now (I believe since Season 19, when I started playing).
Kind Regards
