When a deal with custom tokens gets copied he won’t remember the custom token that are configured.
All custom tokens will be ‘Unable to resolve’
It would be great if this can happen.
Furthermore if you wan’t to connect the right property we can’t delete the ‘unable to resolve’ property and connect a new one. When you configure a property you are also able to ‘remove data token’
Is it possible to remove ‘Unable to resolve’ as wel. It would already saves a lot of time!.
