Help! App widget disappears after changing variants (Textbox)

Hello, I need as soon as possible a solution for this problem: I installed an external app called Textbox, so my customers can add a customized number with an extra cost. When you enter to the product it displays correctly, but as soon as you change a variant (color, for example) it disappears. Any idea?

Website is www.kornerlabs.com

You can check for example this product:

https://www.kornerlabs.com/products/camiseta-betis-manquepierda-laliga-classics-futbol?variant=46526797021523


Also few weeks ago something similar happened to my variants too that i managed to solve but i dont like the solution: I have for example shirt colors (A & B) and for each color i have three badges (X, Y and Z) except that for color B there’s only X and Y badges, because Z is not permitted. Well, the problem came when I deleted that variant of color B and badge Z. What happened to the product is that when A was selected and Z was selected, and you change from A to B, it disappeared all variants and you needed to refresh the page if you want to go back. The only solution I found is to recover that deleted variant and write that I have no stock for that. Any other solution?

Hi @KornerLabs

Seems the app has a bug it removes its input block. But this app has one more bug that is, I can remove your extra cost even after adding the custom text.

using the cart drawer.

Unfortunately, nobody can access the APP code to fix this issue, we can custom-code this whole feature in your theme without using any recurring billing/APP.

And of course, my code would not have this issue too.

Let me know if you are interested in…

I contacted them (Textbox) and they gave me a solution for the first issue, that was my main worry. It’s not ideal but it works. I’ll let this post open in case someone founds a solution for the second issue i mentioned.
