I have the same version maxed on my iPad, and it's old. It was discontinued by Apple a couple of years back. Your device is beyond end of life. It's currently on iPadOS 14.1

Discussions never worked on 9.3.5, Forums didn't show time stamps. Lots of other apps and sites also long ago stopped working.
