Good work. Not sure but it looked like you added your tile directly to the plywood. I do believe you’ll need an uncoupling membrane like schluter-ditra or the tile will crack.
Well, I hope it doesn’t crack but I did Google you can put tile directly on a subfloor plywood long as it’s flat long as the tiles are supported in the corners but living you learn if they start cracking I’ll tear it up and put a membrane down. Thank you.
