my sidecar no longer works

jaybre007,

Thanks so much for answering those questions.

Just to confirm, it sounds like both devices are already signed into the same Apple ID account at this time, is that right?

If you connect your iPad to your Mac via USB, are you able to use Sidecar that way? "You can use Sidecar wirelessly, but to keep your iPad charged during use, connect it directly to your Mac with the USB charge cable that came with your iPad."

Since it sounds like the issue began after updating, would you mind confirming which software versions your devices are running at this time?

Here's how to confirm the exact software version for your iPad: Find the software version on your iPhone, iPad, or iPod

Thanks!
