I've made a test purchase this morning but I didn't receive any notification from Sandbox. Is this kind of failure happening to someone else?

I was trying to send a reply in URL https://developer.apple.com/forums/thread/657081 and after loggin in, the Reply button disappeared. Does anybody know why? I've just registered in the forum. I've found an working alternative URL for sysdiagnose in www. jessesquires. com/blog/2018/02/08/how-to-sysdiagnose-ios/ (the ones in the forum page don't work). In that page (I had to break the domain because the forum doesn't let me send that URL) appears https://developer.apple.com/bug-reporting/profiles-and-logs/?name=sysdiagnose as the right URL for sysdiagnose. Kind regards, Oscar P. D.: I have added a tag because I need at least one tag to be able to post in this forum, but I couldn't choose a right one because there isn't anyone that fits to my question.
