Can't add new backgrounds to my art catalog

Hey! Is anyone experiencing the same problem as me?

I’m trying for about 15 minutes to add new backgrounds to my art catalog but it won’t let me load them after I pick a file and click “send” on my laptop.
Files’ size is not a problem since they are all the same size.

Have a good day/night!

I kinda faced a similar issue where the ‘send’ button just stopped working. I ended up trying a different browser which worked.

I was adding backgrounds on my mom’s computer and had the same issue with chrome only. I ended up just using Firefox and it worked fine. My own computer works as well so I’m not sure.
