I have made many Web application. in this week i have updated the arcgis pro into 3.1 and i was trying to update the web map making some changes. so i made changes and overwrite the map. now each symbology comes in grey color. earlier it was working fine. I was able to overwrite with different different sysmbology. but now i am not. Can anyone suggest what to do. how to resolve this issue.

I am having the same issue, did you ever have any luck with this?

Once you added layer into the map viewer. you have to go in  Map viewer classic. click on the change style layer and click on the set default style.it works.

Was there ever a solution?

I spoke with customer service and they told me that I was using the wrong app builder. Instead of using 'Instant Apps' or 'App Studio', which are now going out of date, I needed to create the application in 'Experience Builder'.
