I was creating a new gallery for my more formal website when I noticed that once again Adobe Lightroom Classic Cloud Sync has stopped working.
As you can see above, I have blogged about this before and normally just going into to here, then relaunching Lightroom Classic is enough to fix it, but not today.
Luckily there is a hidden button to fix this.

If your on a Mac while in preferences and Lightroom Sync, hold down the Option Key (Alt on Windows) and a Rebuild Sync Data button appears, click on this and your Lightroom will restart and sync will be back working again.
