I am doubtful any changes to WorkApps will happen as it seems it’s full steam ahead on Collections instead. I’d imagine they will remove WorkApps within a few years.
My only hope is it’s mirrored features (and of course new ones as well) before that happens. Our struggle with current Collections is you have to be shared with source data to see it in Collections, (Either to source sheet or source sheet/report combo). WorkApps doesn’t have that limitation and we use a lot of WorkApps for external facing Reports and we can’t share the source sheet due to sensitive nature or security. Hopefully that will change as they keep developing Collections. Until then I tell my users not to use Collections as it doesn’t work for our needs.
