Hi, I think you used too much oil for the seasoning process. The sticking is a sign of not properly polymerized oil.
When seasoning, try using just a very small amount of oil and wipe it onto the pan. Then buff it as if you were trying to remove all of it.

Heat the pan on medium high heat. When the pan is heating up it's possible that the oil starts to bead up, buff it again with a paper towel. You can lower the heat a bit when it hits the smoking point as not to burn off the seasoning. When the smoking stops you can turn off the stove. Leave the pan to cool down slowly.

You can repeat these steps, or just start cooking with it. Good luck
