Background app refresh inconsistent
Hi,
I have an iPhone 13 Pro with latest iOS, few months ago my background app refresh has stopped working. I don't get any notifications unless I open the app(WhatsApp, Instagram, mails, Teams, etc...), maybe once in two hours it does work and it also inconsistent. I tried everything suggested on the web, including resetting all settings but nothing worked (did not factory reset the device). Low power mode is off, when I exit these apps I dont close them but swipe up as usual so in theory they continue running on the background, all settings have been checked, apps are up to date, using latest available iOS 16.6.1, happens both on wifi and cellular, all apps are set to use cellular anyway, and low data mode is turned off, always
Any suggestion to fix this?
Thanks!
iPhone 13 Pro
