Currently your capture one pro library cannot be read on capture one mobile with external hdds ability to work on ipad and mac i think having a seamless library that can be used on any device will solve the issue of having to have two different workflow library to work on it which maybe too tedious to most professionals.
I successfully imported the Capture One iPad library to my Mac, but I encountered several manual and repetitive tasks during the process.
On the Mac, it's possible to save Capture One libraries and sessions to various cloud services, like iCloud.
So multiple platform should be as simple as allowing Capture One for iPad/iOS to open libraries and sessions from any location, including cloud services, rather than being restricted to the default local option.
