There is an issue with the buzzer system: it doesn’t seem to call out. Therefor, the whole access system is not working.
So, unless someone is at the space, or you tailgate in, chances are slim of actually getting into the building.
This might sound obvious, but if someone does get into the building, and into the space and switches on isvhsopen.com, then your best bet is to call the space from the front door and have open the door for you.
I already reported this issue to the building manager, but no updates yet.
