No logs from iphone(POST)?

Question

Web development

(There is a site with a script and a bot in tg, through which I receive these logs). Logs do not go to "ios" (tested on iphone), Safari, Tor, Firefox browsers. How to fix?
A site visitor places an order, which consists of two forms, for some reason, on Android, Chrome and other browsers, data comes from both forms, and from an iPhone ... only from the second form.
