Blockscreen empty or blank on Mobile device

Hi,

the blockscreen 'window' (page) seems empty, black on Mobile device(s), here iPhone XR latest iOS.

Cross-test: It works on normal PC, e.g. Chrome latest.

The page loads, then quickly disappears into black screen, empty tab. Page does not contain URL any more, just empty.

In this context (Feature request): I want to change the blockscreen. Is that possible? I don't want users to know about NextDNS, intentionally, as a customer and network owner. (Additional note: I remember OpenDNS providing some sort of contact-form to admin. Would such a thing be possible?

Keep up the good work.

Regards
