Thread titles not changing colour once read

[Queenbee245]

I'm on an iPhone (using desktop site though not app)
When I had previously clicked on a thread, the thread title would com up a different colour so that I knew I had read that one
It's not changing colour anymore though and that's in active and topics

Hello anyone there

Hiya Queen

This will probably count as the least useful answer ever, but I have this problem from time to time. It starts apparently without cause and then stops equally without apparent cause. I don't think it can be anything to do with my customising because I can be having problems on my PC at home but not at work and vice versa (btw I am the boss so it's allowed!).

I have a smart phone but I never ever ever ever use it for MN purposes so I can't comment on that!

Ultimately I find waiting it out puts it right, and not much else.

Hope this helps but I very much doubt it

Well it's worth a try so thank you for replying
It's not really important I suppose but it's been annoying me for the past few days, hopefully it will sort itself out
