I have a very simple Web application published to my Enterprise Portal. It consists of a basemap, and one webmap which contains one dynamic map service (map image layer) with one feature class. The GPS widget is active and the defaults are used in the config for the widget. Devices; iphone 12-14 ios15.xx and 16.xx, safari and chrome.
Symptom: once gps is activated and you begin to pan the map or drive down the road, the map image layer stops loading. It will "hang" with the last set of tiles that were successfully rendered. once the page is refreshed, things start working again until you activate GPS.
Things I have tried: Granting precise location to website in browser. granting "motion and orientation". I have tried multiple web applications with different webmaps and layers. we just upgraded to 11.1 from 10.9.1 enterprise, it is symptomatic in both versions. I have tried turning off "show compass orientation" and "Show location Accuracy" in the GPS widget config.
Anyone experiencing this or have a solution?
