Apple in watchOS10 removed ability to quickly swipe between watch faces on the home screen. For some, it's an improvement (as it was very easy to accidentally change faces), for others it's a massive issue (if you were intentionally swapping between watch faces all the time, i.e. to access different complications).

You can still change watch faces on the home screen, but it's now a bit more involved:

After a ride, Garmin Edge 530 doesn't allow end and save the ride. Activity Start / Stop button beeps on pressing, but doesn't actually do anything. Pressing the power button brings the following message:

Connect IQ app is open
Close the app before putting the device to sleep or powering off.

I use Garmin Edge 530 Cycling Computer and there were few occasions when I needed to download a course from Garmin Connect (running on iPhone XR) while on the road with an activity running on the Edge 530. Normally, when you send a course from the Garmin Connect app to Garmin Edge you need to do a sync for the course to download. The problem is that syncing doesn't seem to be possible while an activity is in progress (the sync just times out or gives "device busy" error message).

Apple made changes to their image and video formats in iOS 11. For photos, instead of JPG they now use High Efficiency Image File Format (HEIF). For videos, instead of H.264 they now use High Efficiency Video Codec (HEVC).

As a result, Vegas (Sony) Movie Studio no longer recognises .mov files created by iPhones and iPads running iOS11 (or imports them as audio-only clips). As a workaround you can tell iOS to record videos in the old H.264 .mov format. To do this go to Settings > Camera > Formats and choose Most Compatible.
