PureGro1: I dont think that WGT removed this ability, Your phone/tablet removed the ability for the double tap to work with this game.
It's happening with too many people with too many different mobile devices to be that.
In their Discord server, WGTNico said that "it's a feature that is unlikely to return anytime soon" and "it's not a priority for the team to fix as of now" and "I think on our end we didn't fully realize how many actually used that function".
