Button which ads new row not working all the time

My app’s URL: https://apartamente.urbanista.ro/

Hey guys,

I have a real estate app where, when somebody presses a button to make an apartment favorite, this also creates a new row in my google sheets file.
This doesn’t work all the time. I have apartments that are added, I have apartments that don’t have rows created for them.

Let me know what additional info you need from me in order to resolve this.

All the best,
Mihai

Can you reproduce the bug yourself and send us a video? Thank you.
