I made a very simple webview only app of my website. For me, everything is working fine. But others got big problems with it.

The registration process seems to be working for me, but others got problems. I have the setting, that registration logins members directly and send them an email about the username and password. In some cases the users get the email with username and password, but the account does not exist in backend so they can not login.

These users sent me the emails as a proof that they have registered. I can see their username and password inside these mails but there are no such users in the backend. So the emails got sent but the user was not written inside the database.

I am aware of the fact, that you can not provide support for a webview app at all but I thought that maybe you got an idea what could go wrong with these settings. I tried to reproduce this many times and can not find anything.
