Does eM Client have bi-directional Google calendar & contact sync yet?

I’ve noticed that a lot of the posts regarding Google calendar & contacts talk about “Sync is coming soon” but as the posts (and dates) progress, they go from optimism to frustration at the lack of bi-directional sync and multiple calendar sync.

Has any of that been addressed and added to eM?

yes, it is already added to eM Client and is working all right (except for Google tasks - we need to wait for their side changes).
