I use this website for a long time.I always got a problem ,I always need to sign up again for next time get on the website,It's a bug or Signed for some Website protection works
When i visit gcad website,no matter how short time i Left,i have to sign in again(but is no problem keep in website )When I turn to the Another website and come back. I Have to sign in again.
Although it's not a big problem,But I'm tired to sign in so many times.
I haven't heard of any such problem from other users, so my first guess is about your browser settings or extensions. Could you try with a different (preferably newly downloaded) browser?
I'm just using the edge my mobile phone and my PC,I haven't tried another,I'm gonna try Google for next time.
