first login (after setting initial password) makes me log in twice

Hi,

First off, apologies, if this belongs in the WooComm forum. I’m new to WordPress and WooComm and set up my webshop at bornefysioterapi.dk. The shop and its payment gateway are in test mode right now as I am testing the customer experience like this: I buy my first product on the page and once the (test-)payment succeeds, I am already logged in. I also receive an email that I should set my first password. Following that link, I end up on the forgot-password page (still being logged in). Now I type in my password (twice) and hit enter. I receive a message that my password was reset and it appears that I have been logged out, too.
All the above is expected, but here it gets weird: if I now log in with my fresh credentials, I am immediately taken back to the login page with no error message, but the same message again that my password was reset. If I log in once more (same credentials), I’m taken to the my-account page.

Any idea, why I have to log on twice? I can reproduce this over and over with new users across Chrome, Firefox and Edge and with all cache-plugins disabled and custom CSS removed (so I’m fairly certain, I should see any error messages, if there were any).

I really hope, somebody can provide a pointer as what I can try to remove this behaviour, as I’m afraid it’ll confuse my new customers and they’ll send me plenty emails about this.

Thanks a lot in advance!
Uwe
