Ability for Calendar filters, i.e. Categories, to support Grid view, currently only supports List view. Feature removed in 16.20 update
Microsoft removed the feature for you to select which Category to show on a Calendar i.e. Grid View. You used to be able to do this by clicking on the Triangle next to a Calendar in the Sidebar which would display all of your Categories. Then you could pick and choose which Categories to display on your Calendar. Now that this feature is removed, you must use Filters, which would be OK but Filters only support List View. Feature removed in 16.19 or 16.20 update.
PLEASE BRING BACK GRIDLINES.
I am working from home and a lot of my work requires scheduling meetings with more than one person and it is impossible to do without separation between the times of day. It's becoming like Russian Roulette, scheduling meetings with people at times I didn't intend to schedule for. It's also very difficult to read email threads without separated lines between the emails. I don't know who thought it would be a good idea to remove these but they are essential to productivity. Please reinstate gridlines immediately.
