Having the same issues here with an iPhone 14 Pro Max which has 512gb, yesterday I only had 3GB left due to System Data filling up I have absolutely no clue how to resolve this issue and it’s a right PIA I don’t want to completely factory restore my phone, because it took about a day to ensure my phone was back to normal with bank apps, authorising apps, etc etc This has never happened before and I’m fuming it’s happening now! I have tried deleting WhatsApp, and that doesn’t work Help!!
