   • Web login form does not load when logging in. Website in general loads incredibly slow.
   • Caldav service can't be found at caldav.calendar.yahoo.com or calendar.yahoo.com

   I was able to set up a personal test account in DAVx5 using https://caldav.calendar.yahoo.com.

   Tested with an Android 13 emulator.

   Footnotes

   1. I used the web interface to change an occurrence of a recurring all-day event to a DATE-TIME event with a different summary text. However, this exception doesn't appear to be synced to the device via CalDAV.
      Making the same change on the device rewrites the event to exclude the exception in the CalDAV version. However, the webinterface is showing the exception as the device has originally created it.
      Exceptions that don't switch from DATE to DATE-TIME or the other way around seem to work fine. ↩
