+1 also very disappointed by the lack of a solution on this issue. This is unacceptable from a company as large as Printful and it leaves a sour taste in my mouth. People have been reporting this issue for more than a year. Your development team is obviously either utterly incompetent or apathetic to our problems because, as a programmer myself, this issue can absolutely be resolved.
At the very least, give us a proper workaround and not the same “not our problem” response that you have been dishing out for months
