BBT, personally, in my opinion, if you can afford it, you would be better off paying Ludwig $50/year for his premium API. The fact is that keeping SNAP Pro compatible with Facebook has been a major headache for Ludwig, because Facebook is constantly changing the API on their end, and thus breaking SNAP Pro’s Facebook functionality. It is probably only a matter of time before Facebook breaks SNAP Pro again.
If you switch to the premium API version of SNAP Pro, not only will you be using Ludwig’s proprietary version of the Facebook API, but it will rid you of the problems you are currently having. Furthermore, with the premium API, you will also be able to autopost to more social networks, assuming that you are a member on them.
Just my suggestion. BTW, I use the premium API with eight social networks, and only one — Instagram — has been giving me, and others — problems as of late.
