There's a new release for this app.
https://github.com/brennoflavio/greenline/releases
Changes:
Support for sending and receiving location messages. Live location are rendered as regular location (only the first update is received) as Whatsapp Web / Whatsmeow does not have full support for live location.
Finished support for ContentHub, now you can send files and media from other Apps directly to Greenline, no need to open the app first
Some dead code removal and cleanups, with the new migration support.
Fixed a bug where clearing data did not delete everything related to the app.
With the new migration system, the app will be slow to open the first time after the upgrade. This happens to adjust the database to the newest code. Should happen only one time, other opens should go normally. This only happens when there's migrations to run, which should be rare after Beta.
