Notion hiked their pricing recently (not great, but oh well) but someone there had the bright idea to slap a giant yellow banner at the top of every page reminding us that said price change will happen - in 2+ months. No way to remove the banner either, after contacting support it was gone and yesterday it came back.

Great when you share notion pages with clients during a video call and that pricing banner hangs around. We are looking to move off Notion now, not because of the banner, but it definitely contributed.
