ECCV 2026 camera-ready deadline: June 27 or June 30? [D]

In the recent Springer/Meteor email, it says:

The deadline for the upload of the camera-ready manuscripts and source files is 30 June. This is a hard deadline and will not be extended.

However, in the same email, the Meteor submission line for my paper says:

submission due: June 27, 2026

A previous email from the ECCV Program Chairs also stated that the camera-ready deadline had been extended to 30.06 AoE and that this deadline is final.

Does anyone know whether June 27 is just an internal/default Meteor due date, or whether it is the actual deadline for uploading in Meteor? Since the email says there is only one upload and the first upload is final, I want to avoid uploading too early if June 30 is the correct deadline.

this is really confusing.
