Pinned frequently used sites in new version of Safari

[JennyWreny]

This is a great new feature which has been introduced in the new version of Safari. You can pin any sites which you like to keep open and they appear as an icon. You can see from this pic that I have Facebook, BBC, Amazon and the other icon, the P is Mumsnet. Why is the Mumsnet icon a P, anyone know? Can it be changed to a M or the Mumsnet logo? Am I doing something wrong?

Hi JennyWreny - we've not seen this one before. We'll have a chat to Tech and see what's occurring. It may be that it's a Safari issue. Thanks for flagging.

Thanks Becca. Certainly not a big problem, just a bit puzzling!
