Zepto Product Personalizer

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

Personalised file that customer creates and is saved in the cart is not editable.
Only an encapsulated pdf or png is available.

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

Every single personalisation option just vanished from the site 1000s of products that had options now have no option for any personalisation. The Dashboard just gives an error and I can only email them to which I didnt get a response to the last email I sent over a week ago which I ended up working out a fix for so Im not holding out much hope for a reply.

DO NOT USE THIS APP. If we could give negative stars we would have. When we used their app, it started malfunctioning our entire website. Our checkout button wouldn't work while we were running paid social media ads. They didn't care. Their team had NO IDEA what to do.

Ultimately, we managed to resolve the issues independently, but this led to the product page displaying incorrectly. The placement of the "add to cart" button was distorted, resulting in a highly unsatisfactory experience ...

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 ...
