One of our customers has Portal 10.6.1 federated with ArcGIS Server 10.6.1.
He has bought for his field workers Samsung A71 with Android 10 on it.
They try to open a mobile application (built on WebApp Builder developer edition 2.15) and he cannot pinch for zoom in/out/pan with the fingers.
The same issue occurs with a built in application in Portal.
Before he had Samsung A5 with Android 8 and there was no problem.
He uses chrome yum, version 220.127.116.11 on Airwatch Browser.
Anyone encountered any limitations with these devices?
This sounds like the pan/zoom issue observed in 10.6.1.
This was corrected in a patch. My recommendation would be to have the customer install the latest security patch for Portal for ArcGIS 10.6.1 which includes the fix for that.
