Cipher Rules and Groups (v14.1.0.2)

Has anyone noticed any issues with

cipher rules

and

cipher groups

in v14.1.0.2?

For example, in the user comments from the following article, it was mentioned that on v13, when making a modification to cipher rules that the changes did not propagate (from my testing on v14.1.0.2, this issue appears to have been fixed)

From what I understand, the use of a cipher group is required for TLS1.3 (client side). You cannot specify a cipher suite string on the client SSL profile when you have TLS1.3 enabled. Is this correct?

Thanks
