Hello,
I observe the same as you for the cancel that creates a scientific war table, and for the leave table switching spectator mode also. For the friend list everything is well on my side, certainly because we don't have the same number of friends.
This is exactly the kind of bug I have just explained. Sadly, I still don't understand what makes suddenly a button no longer working, and even less why it clicks on another button or jumps to the address bar instead. Perhaps it will be gone with iOS 13, or perhaps not.
I don't know well what to do to definitely fix this: Maybe I need to ask a CSS expert, or an Apple expert.
I would be interested in making an iOS app, but I don't know how to proceed. There are frameworks like Apache Cordova, NativeScript, etc… but no one is able to tell me if they are capable of producing accessible apps; and it seems that a mac is required for the final compilation step, and I have no mac; no one can tell me if it's indeed the case or if there's a solution without having a mac. That's two quite simple questions but nobody is able, or want to answer !
As long as Apple and iOS developers in general are so secret and so elitist, I'm afraid not being able to enter there. That's extremely sad; very bad philosophy, but well, it's Apple.
Another possibility: I wouldn't be very happy to leave someone else making an app without myself actively participating in the process, first because I don't have the money, but also because I'm afraid to lose control. IF someone knows a reliable iOS developer ready to make something together for the playroom for free or at a symbolic cost, please tell me; or organize a mass donation. The problem with this approach of giving the work to someone else is to finally get something not as good as expected; for example I have read bad comments about the iOS app of RSGames; an explanation would be he let another developer making the app for him.
