Since the update to 2.3.7 the avatar system seems to be very funky and not working as it was. Can you confirm?

Opera -
you click "edit avatar" in your profile
pop up box shows
you click delete avatar, which deletes it
you choose a file
it shows right on your profile, so you close the pop up box
you can then refresh the page and it shows the old avatar again

Chrome -
user 'a' is not seeing other user 'b' new avatar, user 'a' is seeing the older avatar
Some users on their profile see older avatar and if they click 'edit avatar' the pop up box shows the new avatar

IE11 -
you click "edit avatar" in your profile
pop up box shows
you click delete avatar, which deletes it
you choose a file
new image does not show at all, you need to refresh the page
