iPad update - controls on bottom of screen no longer working

After receiving the new update for my iPad, the bar along the bottom of the screen that includes the volume, pause/resume, forward 30 and back 20, close caption no longer work. I have an older iPad Air that is stuck in IOS 12. and is no longer supported by Apple. If that is the cause, can I revert back to the previous version of the Tablo app? I didn’t really want to go out and purchase a new iPad at the moment.
