just recently we have found that leaving WIFI enabled makes all our apps not load or load very slowly on our S10e Samsung phones. if we disable WIFI, then all apps, such as PGA golf, the Weather Channel and ALL of them do not load. But at that point, we can browse the internet.
This seem counter-intuitive. I have a data limited plan and cannot exceed 5Gb. Up to two weeks ago, we NEVER had this problem.
