1. No, that the "mobile app edit" tag now includes title descriptions from iOS. I'm talking about https://www.wikidata.org/w/index.php?title=Special:RecentChanges&tagfilter=android+app+edit The ones made specifically from the Editor Tasks screen (aka the Suggested Edits feature) have comments "#suggestededit"

2. I have not yet broken down the stats by language. I am comparing the stats across all languages together.
