Some apps do not connect to web via lte
Some apps (always LinkedIn and Words with Friends and sometimes others likeYahoo News and Smart News) will not connect to the internet via LTE. It wasn’t always like this and started several IOS updates ago, I don’t know which. The app developers say it’s not the apps because they are designed to connect via cellular data. AT&T says I exceeded my data limits, but 0.7 GB used is significantly less than my 11GB limit. They also say it depends on the nearby cell towers, but surely at least some towers in TX, FL, and AZ should have worked in the last month. Since it’s multiple independent apps and apparently not AT&T or cell towers, it must be settings. Cellular data is turned on in settings. Airplane mode is off. What other settings must I check? iPhone 6SE, IOS 15.4.1 plus some earlier IOS versions.
