I am invisible to others

I registered today via my google account. I filled my profile, added a picture and a banner. Followed 3 to 4 magazines in my niche. But: No one, even not my fiancée, can see my invitations, comments or even my profile via the public url. I set all settings to the respective public option. I didn’t add an excessive amount of people today (I tried to add 4 to 5 people including my fiancée and colleagues). I tried setting an individual password instead of the Google login, but it didn’t changed. I changed the public url - didn’t help. I made everything private and public again - didn’t help. I even can’t bu y LI pre miun. They don’t accept my PayPal or my friends two credit cards. All have balance. What’s going on here?

Thanks for your help.
