Hi @Sujan12, thanks for your reply. I tried to open fb://profile from iphone safari and it works great. If I change fb://page/MY_FB_PAGE_ID it doesn’t (only opens the app and shows : " Nothing to display"). The thing is i’m pretty sure that MY_FB_PAGE_ID is correct.
Question 1 : How to verify that my fb id is definitely correct ?
Question 2 : Is this due to the syntax of ‘facebook request’ page ?
I didn’t know that fb://page/ was no longer working.fb://profile/MY_ID works great now, but it seemed unappropriate to me to use /profile in order to display a page. Thank you @Sujan12 you made my day.
