V-Flyer

Morning All
Any ideas why the VS11 timings seem to be all over the place at the moment? I’m a regular user of this route and it’s always been a 1730 departure (subject to clocks moving forward and back) but the departure times are all over the place at the moment over the next week
Can’t upload a screenshot of flight radar as size limits

Info on this very welcome here as well. It’s very difficult to schedule arrival plans when departure is a moving target
