iPad Pro 12.9 2019, updated to OS 13.4.1 and now some keys on my my Brydge Pro 12.9 keyboard no longer function, the number keys 7 8 9 for sure.
How do I return my iPad to the previous OS? Honestly, it makes me wonder if this is intentional to discourage users from purchasing 3rd party hardware that's less costly than the Apple version.

You can't go back to an old IOS.
Which keys are not working?

Wow. That fixed it! Wouldn't have figured that out on my own! And no, I wasn't aware of the Brydge Connect app. Even so, now that Apple has an iPad trackpad keyboard, I may sell the Brydge (no trackpad) and buy the Apple model.
Many thanks!
Glad it's fixed and me and Lotus could help, enjoy your iPad
