Issue occurs only in New Teams: Teams owners are unable to delete a channel when they are using the new Microsoft Teams. If we switch to old Teams or logon to Office.com the user is able to delete the channel from there. The new teams version is 23320.3021.2567.4799(preview). Client version 49/23111630009.
The delete is tried both by clicking on the ... next to the channel and then 'Delete channel' and also by click on ... next to Team, click on 'Manage team', click on 'channels' and then clicking on the ... next to the channel from there. The channel remains and is not moved to deleted channels.

You can delete from old teams or Office.com. Here the channel is deleted from list and moved to deleted channels. if I look in 'Manage Teams'. It is only new Teams where the issue occurs.
Is this an issue anyone else have experienced and have a way to fix so the user can delete directly in New Teams? I have tried deleting the cashe, but still unable to delete using New Teams
Update 12012024
I am now able to delete now after logging out and back in to New Teams. It looks like Microsoft has correct the "error".
