About this Message:

The rubbing alcohol likely damaged the device. The solvent seeped into it. So, you'll have to get a new Smart

Keyboard.

Microfiber Cloth:

Next time you want to go about cleaning it, use a microfiber cloth.

This happens to me sometimes and for me it was because of the USB C power cable I had in my Keyboard. When I removed the cable and then removed the iPad from the Keyboard and reconnected the iPad to the Keyboard and checked that it was working again before reconnecting my USB C power cable again.

Same issue here but my ios is upgraded. I have cleaned contact points w rubbing alcohol and swab. …… any ideas?

I have read on the internet that u can get a free replacement... is that true?
