Have tried three browsers and cleared cache on all but the same thing is happening - no description is visible in the edit item screen (goes from item specifics, condition (New/Used), then straight to price)
(see attachment)

Also it makes it hard to upload new items.

I have tried the android version and it *is* editable, but very messy on a small screen.

I suspect there has been an update to eBay somewhere and it may right itself soon.
