I completely agree with the previous comments and would like to add that the CAA should perform a recalibration before starting any PLAN session, in the same way the auto-focus routine is triggered.
A mandatory auto Plate Solve at the beginning of every session would allow the system to calculate the correct rotation and apply the necessary adjustment to match the framing from the original plan—regardless of when or how the session is resumed.
This is absolutely essential to ensure that repeated sessions on the same target maintain consistent orientation, especially when building up data over multiple nights or when doing mosaics.
It's a powerful feature to be able to frame our targets as we wish—but without automatic angle validation and correction at the start of each session, the risk of mismatched data is too high.
Really hope ZWO can integrate this behavior soon.
Clear skies,
Ignacio
