I have a public (https) app made using WAB Dev 2.4 and the LocalLayer widget. One layer in it is a nationwide vector geodatabase (tiled) that includes related tables. Using Firefox x64 and Chrome x64, the related tables reliably appear in both the Attribute Table widget and in pop-ups for that layer. However, the tables seldom, if ever, appear when the app is used in MS Edge or IE11. I also can't see the tables when the app is viewed using Safari browser in iOS 10.3.3 (on a iPhone).
On rare occasions, the tables will appear in the Attribute Table widget in Edge and IE11, but never in the pop-up for the vector layer.
I have various similar internal apps for which the tables do appear in IE11and Edge, but those apps are on http servers. I have another internal, http WAB Dev app which calls an AGOL web map, and the tables in that one also appear in all browsers.
Has anyone else had a similar issue? Does anyone know how I can get the tables to appear reliably in all browsers? Since the issue is intermittent, it points to some WAB instability with regard to MS browsers.
Thanks in advance....
