< Feedback on Instagram Image Viewer
Did it work before or is this the first time you're installing it? You need to right click to an image from the person's profile and open link in new tab so the URL looks like this instagram.com/p/asdf-asdf-asdf-asdf/ where asdf is whatever the identifier of the image is. Unfortunately it only works like this.
Left clicking and viewing the image from the profile doesn't work. Tell me if this fixes your issue. Thanks!
Not working at the moment
Hope you can fix!
