Unable to pin any tile to dashboard

When I try to pin any visualization as a tile to any dashboard, I received the following message:

Sorry, can't pin this visualization yet. Please try again later.

We're working on this feature. Please send us any other feedback about Power BI.

The thing is, I'm trying to pin visuals that aren't custom visualizations (like a simple line chart). I've tried visualizations that are even currently on the existing dashboards and I am unable to pin them. I have cleared internet cache/cookies/etc., tried different browsers, tried incognito browsing, and tried making a new dashboard to pin to. I don't know why I am unable to pin any new tiles.

It started happening all of a sudden last week and I have not been able to find a workaround. Any ideas?
