May i know was there any other device connected to the computer.
Or was the computer connected to any other network.
Hi: thx for answering!
no other device was connected, and the computer was not connected to another network; it was completely offline.
I've been having exactly this issue which is a real pain as I'm currently trying to edit a wedding whilst switching broadband providers, 2 weeks till I get it back and I can't work!! The main display page freezes and doesn't change with the adjustments, painfully slow to load and switch between images.
iMac 27"/El Capitan/LR CC 2015 2.1
the problem could be the test account to LR Mobile: LR tries to sync but cannot establish a connection. How can this sync be stopped?
