Zepto Product Personalizer

The app does not work and poor customer support.i have asked a question about 2 days ago and did not get the answer yet.
however today the app completely stops working!
I spend hours doing the huge configuration with tones of conditions but I was not able to save the configuration. that's awful!

Wow. So many positive reviews. I can't understand it. We waited several weeks and started paying for the app, set it all up and launched our customisable products only to have the very first order go horribly wrong. We had to apologise profusely, issue a refund and assume we'd lost a customer before we'd even started. Then it took almost as long again, through numerous conversations with several different people only to be eventually told the app was not compatible with Printful.com! Not compatible with one of the biggest POD suppliers in the world?! So what's the point of it then? Please make this clear to anyone else stupid enough to assume it would at least be compatible with the biggest suppliers. Because my time is like a toddler in a tiara... Short and precious (thank you Pitch Perfect!)

The live preview isn't showing on iphones (it works on their demos), so I contacted support for help. Support clearly has no idea... They told me to turn on sticky preview (obviously this won't help, but I obliged), then they told me to change the background image size (obviously isn't the issue, but again I obliged), then when that didn't fix the issue they stopped replying

We can´t install the app. Please help, we would like to install it and use it for our custom products

I wait one week Response!I have a problem with the application.And I wrote to them 3 times.Unfortunately no answer for a week

This app does not work with Shopify 2.0. Unless you know in depth coding, I would avoid this app. I experienced slow communication with their service representatives and the "dev team" messed up the coding in our entire site and we were unable to sell our products for 2 days. We were able to restore to a previous date, but this was a terrible experience for us. Would not recommend to anyone.

Customer service isnt what its cracked up to be. Told me a "web developer" could do it, well that is me! You cant pay everyone in a small business.

I don't know what it is about this app, but NOTHING works for me. The background images I upload won't stay, they revert to the original product image. My placeholder images don't stay in place, don't stay greyscaled, and don't allow me at times to move the ones that are selected.
The worst part is it doesn't even allow me to do what I wanted. We make a product in 3 different stains. We currently have the option to choose 1 of 3 VARIANTS set up, i.e. 3 different stains. I wanted the option for a customer to have a stain selected and be able to customize whichever one they have selected. But there's no where to use 3 separate images for customization, it only allows for one.
Terribly exhausting and frustrating experience. Will be looking for something else.

I installed Starter plan, then I uninstalled it to version up to Stater Plus plan. When I re-installed, I always got the error message "500 - Internal Server Error
Please refresh this page or try again later."
The app is having big issue. Let fix it.
