iPad Keyboard not working

After most recent upgrade, my keyboard stops working daily. Before the upgrade, I left the keyboard connected, but now, more than once a day, I haven to disconnect from the iPad, to enable the keyboard to work again. Is there a fix to prevent this issue?

I have turned off my iPad more than once and while removing the keyboard from the linking point on my iPad isn’t difficult, its frustrating, as this shouldn’t happen. Please advise
