Hi Carm,
Be aware that we’re actually working on the compatibility with this version of BuddyPress. 🙂
However, you’re free to update this plugin, all seems working fine on our side. We recommend you to make a backup before any updates.
Don’t hesitate to report any issue you might face with this version, it will help us to make this version compatible faster! 💪🏻
We’ll let you know as soon as the release of Grimlock for BuddyPress concerning BuddyPress 10 will be available.
Cheers,
