Gelato: Print on Demand

I am extremely frustrated with Gelato's customer service and the reliability of their app. Despite advertising 24/7 assistance, their automated chat box is completely unhelpful. I have been requesting a live person for two days with absolutely no response. Technically, the app has been highly inconsistent. I previously dealt with glitches where my image DPI would initially register as good, only to change later, forcing me to re-download and re-upload my photos. Now, I am dealing with a major issue where my personalization collections are no longer showing up on my website, even though they were working perfectly before. The customization tab is there, but the folder of collection photos is failing to populate on my live site altogether. It is incredibly stressful to have a broken storefront and not be able to get a single human being to assist. I cannot recommend this app until they fix their nonexistent support and syncing issues.
