I bought ICloud and nothing changed on my iPhone storage

I have used 127gb out of 128gb of my iPhone. Today I bought the 200gb iCloud and nothing changed. Most of my storage is used by photos and I don’t even have that many photos and videos. When I open the gallery it says that syncing paused and that I don’t have enough iPhone storage. When I go to the settings the storage still says that I have used 127gb out of 128 gb. I can’t even take screenshots to show you and I can’t delete photos, for example I wanted to delete photos, I pressed delete and nothing happened they reappeared ! What should I do ?
