Do you anyone facing conforming issue in resolve 17 .
None of project in resolve is able to automatically connect .
Same project is easily confirmed resolve 16.
Is there any other solution than down grading

Is conform lock enabled ?

Timeline right click on a clip and disable it, that can be a solution.

If not more info is needed.

Yes already conform enabled, but there is no problem in 16 for same xml
