I am afraid the connection to the cloud is embedded in the V3 architecture and therefore it is not possible to completely disable cloud contribution (for things like endpoint management etc). Having said that, we can certainly look at providing more granularity / options to paid users of what data they want to (or do not want to) contribute as we continue to develop the product. This week release was a very significant one from an infrastructure upgrade perspective but most changes were to building blocks in the background - most of them are invisible / cannot be appreciated by the user.
We are still at 1% of the functionality we would like to deliver with this V3, so you will have to bear with us and have a little patience. In the meantime, feel free to keep using V2 which may better suit your needs at the current juncture. And feel free to provide any (possibly constructive) feeback or suggestion as it’s very useful.
