Several users are complaining about too many banners being shown / banners being shown too many times – sometimes despite having disabled all banner types (e.g. https://meta.wikimedia.org/w/index.php?title=Talk%3AAfrica_Environment&diff=24681882&oldid=24675889&diffmode=source#Banner or https://meta.wikimedia.org/w/index.php?title=Talk:CentralNotice&oldid=24669315 or https://de.wikipedia.org/wiki/Wikipedia:Administratoren/Notizen/Archiv/2023/01#Banner)
I've talked with CentralNotice admin @DerHexer and checked my own cookie settings: It seems like no banner-cookie is being set when visiting Wikimedia projects. This might explain why banners are being shown multiple times without hitting the impression limit. „Blocking“ banners by deactivating certain/all banner types at https://meta.wikimedia.org/wiki/Special:Preferences#mw-prefsection-centralnotice-banners doesn't seem to work as well.
Steps to replicate the issue
- Visit any Wikimedia projects (make sure cookies are allowed in your browser) and visit multiple pages in order for any central otice banners to be shown (e.g. https://meta.wikimedia.org/wiki/Special:CentralNoticeBanners/edit/WikiLovesAfrica2023)
- Check detailed cookie settings of your browsers and look for the cookie name of the corresponding banner (e.g. „WLA2023cookie“) – there should be a cookie if the banner was displayed to you
- Deactivate all banner types at https://meta.wikimedia.org/wiki/Special:Preferences#mw-prefsection-centralnotice-banners – you shouldn't see any more banners as soon as you deactivate all banner types.
