As a PO I am part of a scrum team which has recently lost senior experienced developers with no replacements yet in place. The team can no longer be described as competent. In addition to the 'what' for each feature, without experienced members the team are turning to me to guide them with the 'how'. While I do have technical knowledge of the product, and some development experience, I am not comfortable crossing the line into the how.
Am I being reasonable in this context? Any advice from other POs who've been in a similar situation?
