I have Safari disabled since it does not sync with Chrome on desktop. I am on iOS 11.3. Just updated last night, but it hasn’t worked ever since I renewed my XF license a couple months ago.
I can try temporarily turning off the restrictions I set to disable Safari and try there, but that’s all I’d use it for, if it works.
EDIT: Works in Safari, but I do not like it for the fact the Windows version of Safari, IMO, sucks. No extensions for the sites I most commonly use (streaming site Mixer has a chat extension that doesn’t exist on Firefox or Safari).
