Since upgrading to Lightroom Classic 8.3 (on macOS 10.12.6) I have the following problem: syncing with Lightroom mobile works fine after a fresh launch of Lightroom. But when Lightroom is running and the Mac goes to sleep, after waking up the system, Lightroom doesn't want to sync anymore, it says "Waiting for connection" and doesn't reconnect. But the Mac is online and everything else Internet related works as usual. I have changed nothing on my system besides updating Lightroom and Photoshop. I have found no other way to fix this than to quit Lightroom and launch it again but this is annoying.
