(9)To minimise the burden on competent authorities and on issuers, the date of application of this Regulation should be aligned with the date of application of the requirements laid down in Article 21a of Regulation (EU) 2017/1129. That alignment is to enable the use of the notification portal established in Article 25(6) of Regulation (EU) 2017/1129 to ensure that the information specified in Article 21a(1) of that Regulation is accessible on ESAP.
