Hello
I use windows system
When I upload an excel file in cloud, the connection will be interrupted half way through the upload.
Therefore, I try to use the sav file on the desktop and wait for a long time without any response.
When I decide to open it again, it shows that the file is in effect.

i import a big data 1000 variables and 6600 data
but fail to open no matter desktop version or beta cloud version
