Steps followed by me
1) Created Attachment Macro
2) Had Label defined
3) Uploaded 2 attachment ( one .png and other .pdf)
4) clicked on Attachment icon on top of the page
5) New page opened up showing all 2 two attachments
6) Option to attach available on this page along with option to put comments
7) Uploaded one more .pdf attachment
Issue :
1) Label defined earlier in step 2, does not show up. in label column, so basically autotag of label is not happening if we upload attachment from this page ( page shown on step 5)
2) for .png file, View option is not available on this page ( page opened on step 5)
