Write to see if anyone has been able to verify the following:

When I bought my DP-UB450 a few months ago, I did not connect it to the Internet under any circumstances to prevent any updates. This fact is due to the fear that a new update will spoil the reading of BDXL Discs.

I just checked that this year 2023 they released a new update. The version is 1.21. Has anyone been able to verify if with this version there are no changes when playing BDXL Disc?

All the best.
