Storage Issue

I have Zoom One Pro, and currently am being advised that I am using 90% of my storage, 13.5% of 15GB.  In the Plan Options it advises that One Pro has only 5GB storage, and I've never had an issue with storage before.  Now I have only 9 videos stored where I used to have over 100.  Can someone advise if Zoom has changed it's storage policy in the recent past - like past month?  Thank you!
