I've been using Lightroom and LR CC for many years and depend on it for my work.
I use a very high spec computer running Windows 10 Pro
Recently, Auto Sync has stopped working. This is important in my workflow because the type of images I shoot process require the same initial development.
Manual Sync is working but is not ideal.
Anyone out there have an idea as to how I can solve this?
Could you please tell us which version of Lightroom you are using?
Please follow the steps mentioned below and let us know if it helps: -
Go to Edit, Preferences. Under the Camera Raw Cache Settings, click the Purge Cache button.
Then restart Lightroom.
A corrupt preference file can often result in strange behaviour. If you haven't tried resetting the Lightroom preference file then I think you should give it a try How to set Lightroom preferences
