This link has been posted on some FB groups today which states that documents within EU countries no longer require an apostille from 19th February 2019 although some who have been for MEU1 since, have still been asked for apostilled documents! Obviously if the Brexit goes ahead, it will not apply to the UK (after the transition period if it's not a hard Brexit).

Re: Legalising documents/apostille
We got yellow slips two weeks ago and had to show apostile on marriage certificate, it cost £35 straight from the FO in London.
