I think I've had a senior moment or two. I've just realised that you have to click on to preview to get on to the icons.
That's the trouble (I think) of being a member of multiple forums, each one has it's own way of doing things
I think I'll go and lie down for a while.
Can't find them again. When I click on the three dots next to the camera option there kind of highlighted along with other things underneath but don't work. This is on my Tablet not Laptop.
I had to boot up my laptop to check - on desktop they should be in the normal bar:
On tablet:
On mobile:
However, they are only clickable if you have clicked an empty spot in the post area - if you have an image selected, or something like that - the icons will show, but be greyed out
