Because it’s a slightly older iPad (and I’m not using my iPad as much as I did since I’m doing all the things I did on my iPad on my iPhone now so I’m not buying a new one. I actually only still use it to watch movies on an airplane and to validate any bug reports coming in from clients, like this one). This was a bug report made by one of our customers so I am not sure if it breaks on newer iPads as well. I guess I need a new iPad after all 
The issues occur on stable as well so if those are recent changes I am not sure if they apply.
Maybe someone with a newer iPad can check if this is indeed caused by the older iOS?
You can get points for that
