Substance painter export bug

Not sure if this is a Substance thing or Sketchfab, but it seems if I already have an item for sale in the store, im unable to update the model using the substance painter export tool. I have to remove it from sale and then reupload.

Hmm weird. What happens when you try?

Hi - It throws and error (sorry I should have noted it)

I normally just make it non downloadable and then it lets me. I’ll give it another try soon and post back with the error

Thanks. I suspect it’s due to a change in our API for the store. Substance is probably not sending the correct data.
