Next day. I tried the same sequence as above on the same NoteBook WP0315. The load starts and then stays indefinitely loading (top line running). I cleared Chrome cache. Tried again. Same result. I tried it on Microsoft Edge, same problem. To be sure I tried it on my tablet in Chrome and in the Android App. Same problem!
Then I made a duplicate WP0315(copy) (2.6MB). I could load it in Win10 Chrome, it took some time. I tried a load on the tablet in Chrome. It started and went on for some time. Then sudden error: "Wolfram Cloud is resolving unexpected issues and could not process your request. Pleas sign out and back again.". Then on the tablet in
You only load it once!
I tried other bigger NoteBook files who could be loaded.
Is there some server issue? Time out?
