Are you talking about Lightroom 6.2 or Lightroom CC? If you are paying a monthly subscription fee you have Lightroom CC. A couple of questions:
What operating system are you using?
What are the problems you are experiencing?
Have you tried turning off GPU acceleration?
Have you removed the checkmark from the show "add photos" screen?
Also, be aware that you are not the only disgruntled user at this point. Adobe has publicly apologized and has assured us that these problems will be resolved in the next update.
That's right. Is Lightroom CC. I have an iMac, i don't know what operating system is. But is from the year 2013.
They apologized. Nobody denied that. But how long they will resolve that while I continue paying fot a bad service?
