I don´t want to use Lightroom Mobile and I am not signed in to Lightroom Mobile. I know, signing in to LR Mobile solves the problem.
Same problem here.
This started some days before; never saw it before.
I also do not want to use Mobile.
Signing in to Lightroom Mobile does not mean you are going to share your pictures.
In the upper left corner of the main window near the name template, there should be a dropdown list that has "sync with LR Mobile" as the first option. From there you should be able to turn it off.
honestly, but what, if I do not want to sign in at all? Will I have to live with that message then?
Is this a new way to force the user to sign in?
