I have an iPhone, iPad, Macbook Pro and Imac.
I cannot make LR mobile sync between all. It seems fine between the iPhone, iPad and iMac. Or the iPhone, iPad and Macbook.
Is this a limitation to LR Mobile or am I doing something wrong ?
Is there a workaround ?
Thanks - CARLO
You can only sync "Collections" from one LR Catalog at a time. So what you are experience is as designed.
If you have collections from the MacBook synced and try to sync collections from the iMac you should get a warning that if you proceed the existing synced collections will be deleted.
Your License for Lightroom permits you to have Lightroom installed on two computers with one in use at any point in time. (the mobile apps on the iPhone and iPad are not full Lightroom applications and function via the Creative Cloud subscription)
I do find that you can run both computers at the same time.
However as you have experienced the MacBook and iMac will not sync.
