Beta opt out

Hi,

So I've followed the instructions to downgrade my S26 Ultra from the beta program; opted out via Members app, then using Windows Smart Switch PC attempted to downgrade. However it seems I'm getting stuck on 100% "Checking the Downloaded update files..." popout. This was after being asked to ensure the phone was not in AutoBlock mode.

Does anyone know roughly how long this stage takes, as I'm worried it's crashed. 

Also feedback for the developer of Smart Switch - please give more details as to what the program is doing! A 22gb download for One UI 8 and no speed or ETA is quite frustrating! Just let the end user know what is happening! 

Thanks in advance.
