zCash Shielded Transactions

So, I’ve read the three posts concerning zCash shielded transactions and two say “working on it” but they are dated over a year+ ago and the GitHub link showed the issue closed. My Trezor T doesn’t show support for ‘z’ addresses only ‘t’ addresses on both my hidden and standard wallet. Two questions: when will you support shielded transaction with z addresses and (2) if I have someone send me cash via a shield ‘z’ address will the wallet and the Trezor suite reflect that transaction?
