I trying to figure out what could be causing this issue but I haven’t had any luck. When you click the variation selector on mobile it doesn’t drop down till you click it a second time. I am guessing that there is some custom code we added that’s causing this as this doesn’t happen on a fresh install of GP.
i tested on iPhone iOS 15 and i don’t have an issue with the variation selector ( or any buttons opening ) – generally when this kind of thing occurs is either:
a) an optimization plugin is delaying scripts until user interaction.
b) a custom hover style has been applied to the element.
