Hey @Aman_M and @farmerjoe!
Sorry for the delay in getting a fix out. We missed the window for the 1.52 stable version so had to wait for the maintenance release. That said, all zksync issues have now been resolved on all channels including the latest 1.52.x release.
As @Aman_M already figured out, there was something wrong with EIP-1559 - mainly that zksync nodes do not support a standard ETH-JSON RPC method necessary to compute priority fee, so we had to find another way to do it reliably. Here’s the issue if you’re interested in the details. 
Please let me know if still see any other issues. We have landed bunch of performance improvements on nightly, so the UX for zksync (or any other network with slow public nodes) would be a lot better on 1.54+.
Cheers, and thanks for your patience!
