That is a good question. Can fixes (not changing the model so not requiring re-certification) be made to the lambda function without affecting the eligibility of the submission. Stefanie, could you please comment?
The rules say: "Makers will be allowed to make minor changes (such as bug fixes) during the Certification Period to move through the certification phase.". This may be somewhat open to interpretation as we are as of today technically still in the extended certification phase for some of the skills, so a clarification would be welcome.
