To ask wtf is going on with the flashing????

[Rm2018]

Why is there black flashing at the top if mumsnet pages??? I suffer from epilepsy and will have to stop using mumsnet if it doesn't stop :(

I haven't got it

I keep getting it, I think its certain banner ads - I refresh the page and it goes but it isn't ideal!

Me neither

@Rm2018 might be worth reposting in Site stuff, as there are threads there already about pop up ads. I’ve had a bit of the flashing but mostly pop ups.
(Not that MNHQ have bothered to respond or sort it out yet....)

Yes I've noticed it on my phone. It's really annoying.

I get it as well. Galaxy S7 Edge.

Yes I get it too, very annoying

I've got the Tutankhamen exhibition ad at the top of my screen - Pixel 3a - and it is intermittently black.

those velux windows ads were awful for screen flicker
OP I feel your pain YANBU
