Duplicate emails

[JH61]

Since yesterday, every email that has arrived in my inbox is duplicated.

So whether its a marketing type email, business related or personal email to me, I am receiving two of them at once. 

I'm not sure if it's a Yahoo fault, a sky fault or if I've somehow instigated this.

Either way, if anyone has a suggestion on how to rectify this, I would be very grateful.

Thanks

How are you accessing your emails so do you login in here or use an app:

https://skyid.sky.com/signin/email/

[JH61]

Yes

I have Sky .com as an opening tab on chrome and then sign in to skyemailusing the sky drop down menu on the top right.

Do you also access your emails on any other devices ?

Have you checked that any filters you might have set up could be causing this ?

 I check emails on my phone and  on my laptop sometimes. I dont think I have any specific filters.

I was trying to check how I can change my autofill settings recently as my email address autofill had started showing  two full stops in the address, which was annoying. I know I logged in and out of chrome and gmail. The email address  I use though is a sky.com, not a gmail one.
