Glow is one of the latest instances. They paid the actors for season 4, but never produced season 4. It left with a very unsatisfying ending.
Will I ever recommend anyone with Glow on Netflix? no, because I can't tell them "Hey, watch this show on Netflix, but it doesn't have an ending and likely never will"
It's similar to how I'll never recommend The Kingkiller Chronicles or a Song of Ice and Fire. Because doing so would mean that someone reading those would probably never have an ending.
This is where I feel Netflix is hurting themselves. They're producing all this content and then never finishing it. Their catalog is going to start looking like a bunch of incomplete shows.
I think it's fine if you have a show with a short run. One season that finishes properly? Great! Two seasons? Great! but ending before it finishes is just as bad as continuing on forever with no end goal.
