Glad that everything is running smoothly on your side. I have some reports of slower performance on some parts of the world that I'm still trying to get more info on.
Regarding the uploading sizes, I'm yet not sure if higher resolutions than about 15 Mpixels are supported or not. I'm yet to test it and to understand where the limitation comes from, if from the server or the software. I do have more controls on this new server, regarding uploading sizes and memory & timeout management. The problem was always the resolution and not the size of the file but if you make a test, let me know of the results.
And thanks on the feedback!
I just tested the upload of a Lumia 1020 34MP picture and it didn't worked. Like the previous server, it uploads it but unlike the previous one, it stays on a blank page and then nothing. If I remember correctly, the previous server showed a message after uploading the file that said it was too large.
I'm going to test the same image with less and less resolution until it's accepted. I'm thinking 30MP then 20MP, if it works 25MP, etc.
Do you have any news regarding the limitations of the new server ?
UPDATE : My tests are done and you were right about the 15MP limit. The picture just above 15MP didn't work but just below was uploaded correctly and displayed in the gallery. I removed it since it was a test.
