The country name 'United Kingdom' becomes #UnitedKingdom in all our articles and messages. Hashtags like this are used a lot. To create these we need to eliminate spaces from the country name. In NW Online I used to do this with a regex action and replace the pattern s (space) with nothing (empty replacement text).
In NWC the Replacement text field is now suddenly mandatory.
Is this a glitch or does anyone know another easy way to achieve the same result?
