When buying in an online store through Privat24 from a phone, I don’t receive an email about the purchase, but I receive it through the PC version, what’s wrong?

The question is not even what is wrong, but how is this possible, technical support workers answered modestly that Privat24 is not supported and everything goes through LiqPay, but since the plugin itself works, I want to get to the bottom of the truth.

Answer 1

I personally don’t see the function of sending a purchase message to email in this plugin at all, most likely woocomerce does it yourself and you need to dig there. In addition, you did not specify the mobile version with a separate back? Then it would be quite logical to delve into the code of the mob version.
If the adaptive version, then in principle you cannot have such problems, the only thing that comes to mind is either enter the email incorrectly from the phone, or hide the field during adaptation and it remains empty.
Or is the question about the check? who sends private? If so, then nothing depends on you here, and from memory, it’s true that likpay or private has never requested mail on mobile devices, and you certainly won’t be able to influence this in any way and it doesn’t depend on your plugin.
In general, more questions than answers, as you modestly described the problem.
