I've noticed that once a release date is added to the section "Release Calendar", from GX corner, its release date is not updated in case it changes.

Examples of games that had their launch delayed, but in the GX corner they were not updated:

• New World - pushed to 2021, but in the Release Calender it still says 25 August

• Serious Sam 4 - actual release: 24 Sept, GX Corner: 24 August

• Kingdoms of Amalur - actual release: 8 Sept, GX Corner: 18 Aug

• and of course Cyberpunk 2077

I find the release calendar a nifty little feature, with the condition that it's maintained properly. Otherwise, it's just confusing.
