iPhone 7 Gear Icon
Received the last system update, mid November.
Gear Icon never stops. Every app is sluggish to activate, and work.
Called Apple Help one night, they suggested to do a forced Shut down. It worked for a few hours but the same issue came back.
Don't know if this is related, under Settings/Cellular Data. Each App shows the Data usage over a period of time. "Uninstalled Apps" is taking up Data, but no one can tell me what that is or how to eliminate it.
iPhone 7, iOS 13
