Hey. I’ve come up with the solution. I had the issues with other data occupying more than 15gb on my iphone. So the trick is, you need to go to settings<safari<clear browsing history and data. And it clears that space. For me 14gb became 0kb. Like it clears all history, cache files, cookies and temporary data. This is the fix. 100% it’ll work. Have a great day!
