P Desktop: Brown and grey tiles in Library
Hey everyone, some (not all) of my folders look like this. It is on all devices. (IPad, Windows 10 Laptop and Samsung Galaxy S8. This is even the case when I log on directly through lightroom.adobe.com.
However, when I edit a picture it appears normal again. Also when I export the picture is not broken. Any idea, how I can solve it. It appeared after I got a new IPad and reinstalled Lightroom. However, this could be a coincidence.
Screenshot of the problem below.
Thank you for your help and best,
Heiko
