my Apple Watch series 3 is stuck on the apple logo and not coming up

This has been occurring recently with Apple Watch Series 3 models. Try holding down the Digital Crown and the Power button. If you can get it to turn on, update to the newest WatchOS version. Once you download, the update, it shouldn’t happen again.
