I've had a Pinterest board for years where I put book reviews - image of the book cover plus a few words. I have a book review board for each year and 12 sections with books I've read in that month on them. I started to update it late last year and it seems to have gone nuts.
I can't even save a pin. It asks me to publish rather than save and then I get a notification that there are no pins in that section when I have just saved one. (or published). I think I have lost the plot.
