I have seen posts similar to mine, so apologies if I'm being redundant, but I have an issue I haven't seen addressed.
I'm just looking into Power Apps now, and when I logged on yesterday, I saw that we had about 4% of available storage remaining. I added a Per App License, taking me to 1.05GB capacity, it is now showing me over-allocated by 8.84%. I don't know if adding the license took me over capacity in some way, or if it's even related, but I actually had more available before I added it.
I've spent hours trying to figure out what exactly is stored in the database and its purpose. When I go into Storage Capacity > Details, I get the following:

This does not match what I have seen in other blog posts and things to help sort out what you've got stored.
I understand that an environment can take around 1GB of database storage, but I don't understand why my storage increased so much so suddenly. I think I'd like to keep under capacity for if/when we start adding apps here. What is going on, and how can I figure out what is using my storage, or does it matter?
