Trying to upload Fusion 360 f3z file (example Knee Panels) however the progress bar has not moved & seems frozen. I have tried it multiple times and even tried clearing cache. Nothing seems to help. Any suggestions on how I can speed it up please? I even tried unzipping zip (f3z) files but that created a different problem - file names were strange and AutoDesk complained bout access rights and did not upload everything; plus there were two Jason files too I am clueless on those files.
