πŸ’³ The 212 card spending pot is here!

As the T212 card will only debit from the spending pot which will be mandatory end of this month I have some questions:-

if my spending pot is all in Β£ (I live in the UK), and i go to a supermarket in france and want to use the card to debit euros, can I still do that even if I have no euros cash in my spending pot? but i have plenty in my Β£ spending pot?

if no, then I guess there is an FX fee to transfer Β£ from Β£ spending pot to go into the euros spending pot? currently there is no FX fee.
