Cant delete mail storage on Iphone
Im trying to free up a bit of space on my phone, I use a different mail app so ive been trying to delete the native Iphone one because for some reason it is taking up 5 gigabytes. When I hit delete it will load for a moment, take me back to the previous screen, and clear none of the storage. In addition the corresponding mail icon has disappeared. Ive done this maybe 15 times, ive tried restarting my phone and retrying but nothing is working. Ive included pictures for clarification.
iPhone 11, iOS 15
