Zepto Product Personalizer

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. Currently looking for another app urgently that can bring the personalisation back to the site so we can receive orders.

No app has ever frustrated me this much. It caused issues on my product page, and no one is fixing it. I just want to delete this app now.

I am trying to use this but am stuck and it takes 12 hours for a person to respond, ask a question, and then another 12 hours. And their tutorials are from 4-6 years ago, different version.

Ich habe leider immernoch ein schwer wiegendes Problem, vom Kundenservice bekommt man weder Hilfe noch überhaupt eine Antwort. Wirklich sehr schade

It's been many days we are receiving less orders than usual without any reason, so we increased our advertisement on social media with little result...
This morning one of our collaborators discovered that many products (it seems randomly, there is no criteria we can explain) are affected by the error of not showing the preview and blocking the possibility to buy or the font is not working properly.
I made many videos and many screenshots reporting this problem.
I append Video 1 here:

For this problem We lost and We are losing orders and this situation is unacceptable!

It's giving direct error! It is not loading on the website, and when entering the application it gives error 500 or this error: Connection failed: Too many connections. This error is directly impacting sales!!!

Often modify a place, but other problems that did not work. After the modification, the relevant functions were not fully tested. More than one month has passed, and the communication response is slow！！！

I WOULD SAY THAT THE SUPPORT FOR THIS APP IS VERY POOR IT TAKES A LONG TIME FOR THEM TO RESPOND AND SOMETIMES NOT AT ALL, VERY DISAPPOINTED THAT HAVING SPENT A LONG TIME GETTING TO GRIPS WITH THIS APP, THEY NOW TELL ME THERE IS A LIMIT TO THE NUMBER OF PRODUCTS I CAN HAVE, IT IS EXPENSIVE FOR WHAT IT IS AND THE SERVICE YOU RECIEVE

When this app works, its great.
Unfortunately, it regularly breaks. eg uploaded fonts suddenly don't display correctly after working for months/years. Advice from the support team is "just re-upload the font with a new name". That's fine, but why did it break in the first place?
No warnings that it's broken, other than emails from potential customers. I wish I could rely on it to work consistently. Unfortunately I will need to be looking for a more stable solution.

We were initially excited about the app because it did most of what we wanted. However it has a habit of freezing up and we can't upload large photos.

Support has been of minimal help.

Thanks
