Problem adding SmartThings to Designer project

Good morning. I am new to THR. Starting on the Designer first time.

On adding a SmartThings device with old Access Token, the application said “No New Devices found”.

On creating a new Token, the designer threw up an error “This type of CollectionView does not support changes to its SourceCollection from a thread different from the Dispatcher thread”

Please help me add SmartThings hub to designer project.

My PC is running windows 10 and THR Designer is V Windows App (appears this is the only method to install on Win10).

My home is equipped with SmartThingsHub connected to Tasmota devices using Tasmota Connect.


I’ve tried this a few times & have been unable to recreate the issue. Does this happen every time for you? Is this in a new project? Can you try uninstalling/reinstalling the Designer?
