[delta-dev] Multiple notifications for each new message

I often have experienced a pretty annoying behaviour from the android app with the app starting to notify each and every message received even from the same contact. The scenario I'm referring to is usually upon reconnection: if a single contact has in the meantime left me e.g.: 15 distinct messages, I get a raft of 15 sequentially sound notifications which almost paralyze the device. With Conversations if I accumulate 100 unread messages, upon reconnection I get only 1 notification for the entire pack. Is there any "hidden" option/way to conflate the unread notifications ? -- Marco - https://marco.vittorini.org
