Thank you all so much for the info and nice comments, Im glad to say I got it working now. I did notice that the only way my art shows up on my page is if its facebook online full version, which kinda sucks being Im using a tablet.
I had my art stolen awhile so I recommend using watermark or posting your invoice cause there are people that take what they want with no concept of how much work goes into our art.
I will all the best and appreciate the help and the sweet post of my art 😊
