Not sure - it may have been good advice last year but I have been researching options and - although I have not tried every State - the ones that I have all sing from the same sheet - "You no longer have an EASA licence (from 01.01.21) so you cannot request SOLI transfer."
The UK EASA licence is now effectively only valid in UK or for flying G-reg outside UK. To operate anywhere else you will need a validation of your UK CAA licence (when you get one issued). A validation is normally an Air Law exam of the country you want to fly in plus a flight test plus a work visa. I suspect that it will not be quite that straightforward when dealing with our 'friends and partners in EU'.
