heya anyone else having issues with iphones using safari not submitting forms? - works perfectly fine on Androids and on Edge and Chrome - im using 2.9 build 5557

The latest version is 2.20 - 5577. It has been upgraded to be able to handle PHP 8.x

its a very expensive upgrade price just to correct

That depends on how important the form is, most internet hosting services require a minimum of PHP8+
That happened a while ago now and everyone had plenty of time to take the necessary action.

You could try your hosting service to see if they still support PHP 7 but I doubt it,

Althogh I must admit that it's a bit weird that it works on Android and Edge if your hosting service is still letting you use PHP7 then it must be some other setting's that are effecting Safari, and I am not a user or fan of Apple stuff so wouldn't have a clue as to what it could possibly be

Actually, it wasn't really a 'correction', but an upgrade. PHP8 didn't exist when the version you have of WFB was launched. Since then the PHP has changed, and those who produce software have to keep up with upgrading.
