Lately, I am observing a slow down in the loading of maps on the center console. I am observing too many gray checkered boxes lately. They appear often while driving, with no touch input made. Sometimes even an area that is already loaded disappears randomly, and then takes a while to reload. Also, I noticed that it takes longer to load after zooming in and out. LTE signal strength seems normal, and I drive the same route to work every day. I do not think the issue has anything to do with poor reception, and have a feeling this started after the 8.1 upgrade. Anyone else see this?
