Received the warning about EU domains a few days ago. Not a brilliant piece of communication, as it didn't seem to say what the timescale is for re-registering an existing EU domain with an EU(non-UK) address ?
There is yet to be a timeline established as it is not in our control, but that of EURid, the Registry. The situation is quite fluid as the final timeline depends on the outcome of the ongoing Brexit negotiations between the British government and the UK. We have provided as much information as is currently available through the email that you received.
