Request Access to a shared folder. I'm confused.

[AppleBebe]

In my Notification Area, I can see that someone has requested access to a particular shared folder.

After I have approved them by clicking on the blue APPROVE button (in the notifications tab),  it then brings me to the actual folder that I am sharing.

I get a pop-up window with their address (pre-written) and I have an option to write them a message.

I'm confused because I thought I just APPROVED them with the BLUE BUTTON. Why would I need to this email ?

or is it just a confusing 'user-interface design' where the BLUE BUTTON is totally meaningless and does nothing ?

Please someone advice me.

Hi @AppleBebe; welcome to our Community!

I'm not really sure what exactly you're referring to, can you please forward me a screenshot of how this looks like on your end so I can have a visual too?

Thanks a bunch!

Hi Walter,  (thanks for responding).

Here are TWO screenshots:

The first one shows that 'Carol' requested access to my folder, so I CLICK the blue button to APPROVE her.

After clicking on the APPROVE BUTTON, I get a pop-up window where I can write a message to Carol.  (*see below)

So, (my question),  Pressing the first APPROVE button has already approved Carol, so why would I keep getting a pop-up to write to her.

it makes me feel as if the Blue Approve Button didnt work. or is Approving someone a two-step process?   Why is it almost forcing me to write a message to her.  I dont want to write a message to Carol.

There is no mention what this pop-up window is actually for and whether its important or not.
