Options Trade Builder is gone with no explanation

The sole reason I kept using the classic ATP was for the Options Trade Builder. As of today, it's gone from the software. I contacted Fidelity - no explanation.

This was VERY useful. I don't know of any other tool or website that can map out the matrix of options in that way. Columns: dates. Rows: strike prices. The numbers that made up the matrix were the value of the calls or puts.

BRING THIS BACK. Do Fidelity's software developers just get bored and take away random features when they feel like it?
