Unable to use Session & User events in Mashup Builder 8.4.x

Hi!

I don't know if it is a bug or 'feature' but Session Propoerties & User Properties in mashup events are no more available. We migrated to the 8.4.2 version and most of our mashups are broken.

I didn't find any Realese Notes either opened tickets about this issue. Any ideas when it will be fixed?

Regards!

Adam
