This is interesting. I have not had any reports of this from clients, but myself just yesterday in Excel (Office version 16.0.15726.20174) had a popup that the clipboard was not available when cutting a cell to paste into a new location. I basically ignored it as a one off issue. VDA 2203, Windows Server 2019, Seamless Apps, Workspace App 22.10.2.21 (2210), FSLogix 2.9.828.50276, Virtual Channel Policy blocking configuration disabled.
Will be keeping eyes and ears open for more reports of this.
