Gelato: Impresión Bajo Demanda

I have been a Gelato customer for nearly a year with over $125,000 in sales this calendar year through their platform. Until recently, I have been largely happy with the service — product quality has been consistently good and the platform generally works well.
That makes my current experience all the more frustrating.
For several weeks I have been completely unable to publish new products to my Shopify store without performing a "Sync Products" action for every single product I attempt to add. I have contacted support at least six times, worked through every troubleshooting step suggested, and currently have open tickets with no resolution. The last two support representatives I communicated with stopped responding entirely and never followed up. Now, the situation has worsened — product sync now freezes at 1% and will not complete, leaving me fully blocked from both publishing and syncing my store.
I understand technical issues happen. What is not acceptable is weeks of silence, ghosted support agents, and open tickets going nowhere. New designs I cannot publish are revenue I cannot generate.
I am giving Gelato one final opportunity to resolve this before moving my fulfillment to another platform.

Hay Variedad de Productos y muy intuitivo a la hora de trabajar y seguir los pasos.

Estoy super decepcionada con Gelato, al principio la impresión y el material era bueno, pero no sé que ha pasado que es horrible, la impresión viene con puntos y filetes, a veces la impresión es con DTG otras veces es un transfer, el envío cada vez es más lento, al principio tardaban muy poco en el envío ahora mismo es súper tedioso de 10 a 13 días. Los que tenemos tienda online bajo pedido no podemos esperar una buena calidad, es una loteria. Y por supuesto si los clientes se quejan adiós clientes, eres un pésimo profesional.
