Thanks so much. The waffles were so delicious !! I can’t believe how great they are.

Thanks for your question. In addition to a few ideas I outline in an earlier post with vegan waffle baking tips, here are a few additional thoughts:
-Re: the right amount of oil, I generally use a pressurized spray can of canola. For a round iron 7 inches in diameter, I spray each grid for a total of 1 to 2 seconds, making 6 to 8 quick sweeps across each grill in a zigzag pattern to cover the whole surface. Too much oil can also cause issues (this is why I never recommend brushing oil onto an iron).
-For an iron whose size is equivalent to a 7-inch round iron, you probably want at least 1,000 watts. Lower-wattage (and thus often lower temperature) irons can have a greater tendency for sticking.
-Flaxseed is a wonderful binder, but its binding and thickening power can increase as a batter sits–to the point of binding with the iron slightly. Without adjusting the time you were allowing the batter to sit previously, try decreasing the flaxseed by a small amount (by 2 teaspoons or 1 tablespoon to start) or increasing the water by a small amount (1 to 2 tablespoons to start) and see if that helps.
