Yeah, some of this stuff is going to happen and it's a hassle dealing with it. However, and this may not have been the case with you but has happened where I work: If no one is satisfied with the tools they use then maybe the selection process isn't properly taking user needs into account. You, for example, may find Zoom's meeting ID/participant ID system onerous, but if the bulk of your users need or want something else, there's a problem: Smooth comunication with potential clients through a tool they're comfortable with is rather important. Personally, I can't stand the parade of different conference tools that require their own browser plugins or installed clients or single-use download client etc.
