- session_id: include session_id as a param, so that measurement protocol events appear in session-based reporting
- user_id: previously, if (a) app_instance_id/client_id is sent without user_id and (b) measurement protocol events are sent with app_instance_id with user_id, the MP events weren't being exported to Ads properly. This has been fixed so that now the measurement protocol events are exported and attributed.
- Conversion events no longer need to be sent with an 8 hour delay.
- Updated naming from App + Web to Google Analytics 4.
