Slim folio

More along the line that Apple may have changed something and Logitech needs work on their keyboards to make them compatible with any changes Apple may have made.

Apple does not alter their operating system to accommodate third party stuff, it’s the other way around.

So perhaps reaching out to Logitech?

I would still check the batteries.

Am having the same problem as you this happened after the software update thinking maybe the iOS software is not compatible to slim folio

Did get in touch with Logitech they said it was the update software the root of cause problem

Still, Logitech needs to fix it. Apple will not alter their iOS to suit a third party company

Why was it functioning all very well before the update.After the update it stops working can only assume that Apple are at fault since the keyboard is not programmed.

I can’t tell you why. I’m just a person like you. All I can say is that Apple will not go back and alter their iOS release to make a single third party keyboard work.
