iPhone storage saying less than true value
after the ios 15 update, my iphone has been miscalculating the storage space on my phone. it says that i have 62 GB of 64 GB available when right off the bat, my top two apps take about 10 GB of my phone capacity. although I should be happy that I have "extra" space, it's misleading and I'm not sure how much I actually have left to spend on capacity. please help if anyone knows how to fix this.
