please do not post the same question multiple times in different places. once really is enough.
thank you

a few things:

generally: ignoring a couple of css declarations (mainly distinctly setting cursor:pointer for a few elements) there is no code anywhere that distinctly targets iStuff or non-iStuff, so it does not make much sense to me when you say that some things do not work on your iPhone (but i cannot speak for any other plugins or the theme you are using as those might of course change things)

> Pre-order: 15 minutes before the closing is not working! You can place orders until closing time.
you will always be able to place orders when you are actually open at that time (otherwise there isn’t really any point of having the shop open at that time in the first place) , the “15 minutes before closing” only applies to preorders in/for the future (i guess i could make this a bit clearer perhaps)

>Pop-up with Iphone is problematic.
>but height remains small and you can not scroll down.

in the past – with very old versions of the plugin – perhaps. if that were still the case, I am sure I would have heard about it. Moreover, from what i can see on your site this works just fine. I cannot see the problem you seem to be having to be honest. Have you tried a different phone ?
have you tried disabling all other plugins using a default theme ?

>Ingredients pop-up does not work with the long list but with less decay already.
Sorry, but I don’t understand what you are trying to say

re popup:
without a link , I cannot tell you anything

re backup: i cannot help you. it is your backup solutions responsibility to transfer things correctly / completely

you have to speak to paypal.
what it means is that the order did not get processed their end until 2 days later .
this might be for various reasons only they will know (or it might tell you in your paypal account)

you are quite right. I should update that.
things always take a bit longer than thought (i thought i’d have something by september/october)
as it turns out I should have a beta around christmas.
I’ll update the devblog in the next 10 days though to at least list the main addition / changes

you can probably use this as a starting point

sorry, but i do not understand what you mean by “compiled automatically” or what it is you are expecting when and where

until wppizza v3.x, no additional gateways – other than the ones already available (https://support.wp-pizza.com/gateways/) – will be added I am afraid.
Once wppizza v3.x is released, there is definitely a plan to add more gateways in due course. However, which one will be available when I cannot tell you.
In the meantime, there is a skeleton gateway in the plugins add-on directory you could use to develop your own if you wish (wppizza v2.x)

sorry, but that’s not likely to happen anytime soon (if ever)

not only are there so many possibilities and permutations that it will most likely confuse those non-technical users in the first place, but the layouts available will probably also need some tweaking (using css for example) to make them work with the theme used when setting things up
(that’s just off the top of my head, I am sure there would be other things that neede to be considered )

furthermore, there is always a possibility that shortcodes change or – more likely – are added at some point
for instance from version 3.x onwards – when that is released in the not too distant future – you will be able to mix and match layouts for different pages (plus a bunch of other things)
trying to maintain yet another option with the inevitable request for more granularity will take way too much time away from adding other – and in my opinion more useful – additions

lastly, understanding shortcodes is somewhat essential if you want to set up any kind of wordpress site (barring the most basic ones)

that’s not to say I will never look into it, but I just cannot see this happen in the near future

if you are referring to this
>https://support.wp-pizza.com/topic/post-code-validation/
then no, there has not been any development afaik (i.e stripe still do not allow for this sort of thing in the popup ….. unless someone tells me otherwise)
