I am trying to add a new listing, but every time I try to add the photos it tells me they cannot be added at this time. I followed all the suggested solutions to try to resolve this issue, but nothing is working.
Requirements and Best Practices for Images in Your Etsy Shop – Etsy Help
I see your other listings have vertical photos instead of square or landscape photos. That could be one reason.
Even if your photos don't meet best practice you should still be able to upload them. I would try using a different browser such as Chrome as it sounds like a glitch.
