Reproduced with my test account. I changed Einstellungen/Benuzerdaten/Form_der_Anrede to “Sie bearbeitet Wikiseiten” (= female pronoun). On my startpage the tab changes to “Benutzerinnenseite” as intended, but the pagename clings to “Benutzer:MBq-Tests”. Vector (2022), everything on standard, no userscripts.

I could reproduce this bug on the Android Wikipedia app: 1) go to page :de:Wikipedia:Wikimania_2024/Dokumentation, 2) click on „Bericht von Ailura“ (which links to :de:Benutzerin:Ailura/Wikimania_2024). 3) „user page not found“ error, see screenshots. On the other hand, the iOS app works correctly.

Confirmed: five renamings are stuck today, the oldest one started on 4th. Different dates, different size of task. Others work fine. I just added a new rename which ran through in seconds.
@Devs: Could one of you try out these recommendations: https://wikitech.wikimedia.org/wiki/Stuck_global_renames ?

Today a dewiki user complained about recurring notifications which seem to be triggered by a 2008 (!) edit ( https://pl.wikipedia.org/w/index.php?title=Wikipedysta:JD&oldid=prev&diff=15025515 ) on plwiki, rf. https://de.wikipedia.org/w/index.php?title=Wikipedia:Fragen_zur_Wikipedia&oldid=201911169#Fehlerhafte_Benachrichtigungen and his screenshot https://de.wikipedia.org/wiki/Datei:Pl.wp.nerv.jpg . Might be the same issue?

Looks good now: JobQueue seems emptied. I just tried a couple of renamings which worked perfectly.

Here's another one from de.wp:

Renaming back and forth doesn't work ("renaming already running"). Probably user should create a new, slightly different account?
