This started happening to me 1-2 weeks ago. Very annoying. Not sure if it is ad related.
iOS 16.11
IPhone 11 Pro Max
This is constant for me too…this is making the website unusable on mobile. If you put the phone in landscape (to view things like the card upgrade spreadsheet) the entire website is completely obscured.
Thanks for letting us know, we have reported the issue to our ad network.
