I find it does not working very well with me. I had encounter a lot of bugs, tried to contact support but what they recommended me is to delete the App and reinstall it. Totally does not work. I linked my previous page and delinked it, it says the limit has reached and require me to go for paid version so that i can link more pages. Could not solve this issue for long time and I have to delete it and move on.
