Recently, “seen” tags no longer appear on images I have viewed. This is in Safari 14.1 on macOS. It worked until maybe 3 or 4 weeks ago. I have tried disabling all extensions and I have tried deleting all site data and they still do not appear after an images is viewed. The odd thing is that if I revisit wallhaven a few days after I view an image, the “seen” tag appears about 50–70% of views images, but not on all.
Any thoughts on how I might fix this?
