Very disappointing from Craft - I've had to work over the weekend due to a bug. An upload that should take max 15 minutes has taken two days to go through in chunks.
1. Signing in is incredibly slow / non-existent
2. Upload caused my internet to stop working
3. Doesn't say when upload has finished with the error message, 'already_uploading'
The only way I've got Craft working is by restarting my computer whenever I need to upload a change to a screen - which takes ages.
Please sort this bug out ASAP! We rely heavily on InVision prototypes for user testing to the general public.
