At one point Sage's Mike Ritchie indicated that this license check happens differently based upon the subscription term. For a monthly subscription, licenses are checked monthly which means those customers will be the first to encounter a potential issue. For annual or multi-year licenses those are checked at some point just prior to expiration ( I'm not sure whether it's right on the expiration date or whether there may be an advanced check/warning ).
YMMV as to whether all or any of this proves to be accurate. I recommend taking the position that the expiration is September 2023 and customers need to upgrade no matter what their subscription license term is ( note that perpetual may not be impacted).
The Sage FAQ on this issue - Online encryption security enhancements - indicates "Effective September 2023, Sage servers will stop accepting communication from Sage 100 and Sage 300 product versions using TLS 1.0 and 1.1."
