I have been trying to edit some of my listings this morning, but when I tried to switch between the advanced and the html screens the transition takes a very long time. The last time I used it was before the last windows 10 downgrade when it was fairly fast. I have also tried a bulk edit this morning, on a group of 3 listings and that is taking a long time to process, the wheel just keeps going round and round and.....
Admittedly I have not used the bulk edit for a long time but last time it connected to the site fairly quickly.
And before anyone suggests it - I ran ccleaner before I started.
