iOS 18.2 Mail push issue workaround: Is it better privacy-wise to whitelist mask.icloud.com and mask-h2.icloud.com or to put BLOCK_ICLOUD_PR=false in pihole-FTL.conf?

I've noticed that as of today, no emails are being fetched unless I open the Mail app manually.

Can anyone else on 18.2.1 confirm this?

I wonder if it's Apple's servers that are acting up or if it's my email provider.
