impossible to remove a member from a circle

Hi,
I was suggested to 'link back' here from nextcloud forum.

so, let me put it down: in circles, once a member has been added to a circle by the owner, it's impossible to remove this member. same thing for user groups or circles added to another circle.
also circles can't be deleted.
Once deleted, the page refreshed, the user or the circle are back in the list.

It's also impossible for a member to leave a group (error pop-up: impossible to leave the circle 'circlename')

This is on NC 24.0.7, Circles 24.0.1
ubuntu 22.04 apache2 maridb php8.1
safari and brave

THANKS a lot if you can help

Start by tracing the PUT /ocs/v2.php/apps/circles/circles/{id}/leave endpoint through LocalController.php and CircleService.php, especially the FederatedEventService.php call at the reported lines. Reproduce the leave or removal failure and inspect the RequestNetworkException. Done means members and nested groups or circles can be removed, members can leave, and circles can be deleted without returning to the list.
