Hi…,
As mentioned at Navigraph Hub - "Update All" button - #10 by Ian,
“Update All” is planned for a future update of Navigraph Hub, as well as addressing the issues you have mentioned.
That said, the current Hub version is able to update all its included packages, and shouldn’t be so difficult. I also have many packages, and updated them yesterday by patiently single clicking on the Update button for each. For single clicks on multiple packages, the updates occur in parallel with differing times to complete depending on size.
Thank you for your patience. A new Hub is definitely on the roadmap.
Cheers
Ian
