Sadly the authorities are unable to see eye to eye at present so everyone has to suffer needlessly. Things will change again after 2022 as the UK will be taking a hardline stance on the matter also meaning if you do EASA training then you have to go through the full conversion to regain a UK licence. It comes down to either completing both sets of exams / training for both UK and EASA or just sticking with the the one where you have the right to work.
