It would be very useful (I think) to have a setting in a Web Map within Portal for ArcGIS (or in the portal itself) where you could set the default behavior of popups to be set to enabled or disabled, rather than the default always being disabled. Lost count of how much time I've had to spend re-enabling popups in Web Maps when services are added (or re-added) to a Web Map. Apologies if this has already been raised, I couldn't find it mentioned anywhere.
