Hi Guys,after reading all of this I am bit shocked how trillion company could have such bad support. I also tried to buy Enrollment, and tried four times, all times failed and order were cancelled, without any message or information what was wrong.Now it is not even possible to reach to Customer Service. Wrote email last week, still no answer. Now undert contact us, event cannot find phone number.I am from EU, and also having same payment issue. Cannot even imagine worse customer service than apple has. Seems like they are interested only to support their sold hardware, not developers who make revenue for them.Does anyone have phone number were to call in this case to get information what is wrong with payments?

Have places 8 orders till now. Tried different cards, added card to my Apple Id, also made test purchase, it worked.Have no idea what is wrong. I am from EU. Does anybody have phone number were to call to reach Apple Developer support? When I try to open contact page from this page, see only email option.

Hey all, I have also provided feedback in IOS. There is such app in beta IOS versions. With Build 5 it is still not working, and my feedback case still is open. @BartFranse @PolU3417 guys If possible submit also feedback in IOS so they pick this ugly issue as soon as possible.

Forgot to mention that on other browsers it works well both on WiFI and mobile network. My feedback case number is FB15233370.

I found how to get it working using this WA, but it is not fixed in current IOS 18 Beta 7. To get it working, I went to Safari Feature Flags, and enabled and disabled flag - Enable experimental network loader. After that, uploads started to work. From this I conclude, that it is some issue with Safari network loader. After resetting to default settings, It again didn't work, so this is workaround.

It looks that this Feature Flag - Enable experimental network loader is enabled by default, even when it is disabled. When you enable and disable it, then it is turned off. With this feature enabled, uploads from Mobile Network doesn't work, so It is a bug with this Feature Flag.
