Thanks for your answer. My subscription is called CC (all apps). All Adobe web pages can be opened. The performance of https://lightroom.adobe.com/ is really bad. Sometimes I can login, but in the evening (CET +01:00) the pictures can't be loaded at all. See attachment. In the Morning it works fine. Is the Lightroom server too busy at these days?
I am not seeing any problem myself. The only noticeable change is that a page flashes up “The World’s Best Photos are Made With Lightroom” and then the photos appear. Although this only happens in the Chrome browser. Using Firefox I momentarily see “signing in” but then the photos appear. Have you tried using a different browser?
Otherwise you may need to contact Adobe directly to enquire if there are any outages in your country.
Thank you for your answer. I use a special browser called "fully kiosk". I think it's based on chrome/chromium. You're are right, trying another browser makes sense always. But Safari behaves the same way. All other Adobe websites came up immediately. So, I'd would exclude local network problems. Seems to be a Lightroom web issue.
Today it work better. I'll wait and see. If it get worse again, I'll act on your advice and contact the support.
