I'm currently logged in Stack Exchange Network with Stack Exchange account (i.e simply by Email and Password, not through Google, Facebook etc.) Now, if I try to join other community by "Join Community" button, it asks me to singup instead of creating account with existing profile.
When you are already logged in and if you joins the community, system just ask for the confirmation about creating an account and after clicking on that button it should create an account with present credentials. But here I'm unable to accomplish that one.
I've also tried logging out and re-logging multiple times but facing the same problem. So, How do I join new Stack Exchange communities with same credentials now?
System Information: Mozilla Quantum 60.6.1 ESR (64-bit) on Debian 9.8 GNU/Linux. Also tried clearing all data of browser and disabling addons but not worked.
One work-around I found to join particular community is: Logout first and then open the site which you want to join and click on Login providing present credentials and it will directly ask confirmation to join the community and create account But after logging in, you'll no longer be able to join further communities with present credentials.
