Hey there there's a huge problem I'm having I was testing correct sized shirt templates even the default one and when I try to upload the shirt it doesn't work it loads long with a message saying "Error"
Is it just me having this issue or y'all have the same uploading problem?

the same thing is happening when i actually put it in the shop it is not working at all i talked to the polytoria staff about it before, and nobody can actually buy my shirt, sadly
