Plugin Directory: Changelogs not updating on Rosetta plugin directories, Act II

[let me see...]

On WP MS German install, the changelog for plugin updates is almost always one version behind (today: Yoast 5.4 update available, changelog in my backend says 5.3.3 is latest)

Very similar problem to this ticket: #2750

@SergeyBiryukov Isn't the plugin details page in the WP backend cached locally? I see this very often too and had a short talk with @obenland on this topic. I am wondering because if I see there is an update I should see the correct changelog, but I see an old one. Not sure if this is a problem with the translated version, local cache or something else.

The API request is performed by ​plugins_api() via ​install_plugin_information(), I don't see any caching there at a glance.

Then what could be the reason for this behavior? I get a notice about a plugin update, click the details link to open the modal and get an old changelog info. If I switch to the page in the plugin directory there is the newest changelog info and sometimes the info is on local version of the plugin directory (and sometimes not).

I would expect to see the current information in my backend, if I get an update notice. If there is a cache it should be invalidated. If not, I have no clue what the reason of this issue can be ... any ideas?

Caching on the API server I suppose.

Is there a current example we could use to troubleshoot?
