Help me please with support of Microsoft Bot. I can't change Bot Channels Registration password from 29 of December. The mistake is": "There's a temporary problem Exception of type 'Microsoft.AppRegPortal.Providers.Graph.GraphException' was thrown. Error Info: Tue, 02 Jan 2018 09:52:46 GMT | m/Fnb | p9du8". What is the way to fix it?
