- you have to pick a number of tiles to fit on the screen, it cannot deduce the right number automatically
- the selection for this is buried in an options dialogue
- there is no facility to hide participants that don't have video from the tile grid, wasting screen space with useless squares containing an enlarged initial
- there is no way to flip to a second page of tiles if there are too many people to fit on the screen together, you just get a random sampling of call members
- there is apparently no way to drag to resize the space dedicated to the screen sharing display versus the video tiles
There are also other ridiculous limitations and rough edges, like the chat box silently truncating messages at about 500 characters.
It is as if nobody who works on the product is forced to use the thing.
