Members Can't send messages in a New Chennal

[zeeshi92]

Using Team since 2020, Yesterday created a chennal and added members to new chennal, but members can't send messages to this chennal everytime it's showing sending.... then failed. 

Other chennals are working perfectly, is there any permission issue or something else?

Any help highly appreciated.

Hello, you should verify these team settings. If they are OK you best open up a support case with Microsoft (as the other channels work).
