Failure to login (after Apple updated their side to SRP ?)

[crazyelectron-io]

After installing the latest iCloud v3 integration, entering the iCloud credentials fails with the message Login Error, Other Error or iCloud is not Available and the HA debug log shows:

There are reports of PyiCloud not supporting the new SRP-6a protocol now introduced by Apple, causing this issue.

I just wanted to report it here (there is already an issue opened over at the PyiCloud repo) to make everyone aware.
