Error Message

Hi I couldnt find an email I wouldve rather emailed you all 1st but I can update the rating after the issue is corrected. I love this app but as of yesterday Im no longer able to gather my IG post to send its given a forbidden error message. Can this bug be fixed? Ive logged completely out and and back in and its still not working.
