Cannot upload

Hi, I've been having trouble uploading maps and tokens for a while now. I've tried different sizes and formats, but the upload just stops at 60-70%. Can anyone help?

Are the uploads all from the same source (such as a graphics program)? Have you checked your account to make sure  you have enough storage space? 

Yes, I have enough storage space, but I was not awarecthat coul be an issue so thanks for the suggestion. The uploads are a variety of different pictures (e.g. jpg and .png) of different sizes, but none bigger than 9074 kB.  This issue seemed to happen suddenly, and assets I previously were able to upload are no longer possible to upload. I've followed suggestions I found on this forum, but nothing has helped.so far.

Are these images all created using the same program?

No, but mostly from Inkarnate. I used a different mapmaker previously (forgot the name). I have previously uploaded a map from Inkarnate, but the same map won't upload today.

One thing you might want to try, reprocess the images through some other program like Paint. See if they will upload after that.  If that doesn't work my suggestion is to file a bug report with the Devs via the Help Center  as the forums are primarily users helping users. 

I "solved" it, and all the assets I uploaded were put in the art library, but not on screen. That's why I believed that they weren't uploaded, and I wasn't aware that this could happen. But I should have checked there just in case. Thank you for your help and replies.
