We have set the Show Admin Bar for Members toggle to No and the bar does disappear, but the space for it still shows. See the screenshot for an example.
Please register some new testing user and leave the user's login details with your forum URL here.
I've set the topic private, so the login details can be left without any worries.
Also please make sure the issue exists for that user.
Did you guys solve this?
There is no way for me to share credentials either I'm afraid, sorry for this. I hope, however, there will be a permanent fix for this in the upcoming update as there are more of us who are experiencing this issue. Thanks.
