Thanks for the detailed explanation — that’s very helpful. Based on your description, this does seem to align with the second case you mentioned — a mature notarization workflow that suddenly enters the in-depth analysis path. To add some context from our side: we’ve been notarizing successfully via the Notary API in an automated CI workflow for quite a long time without issues. This behavior (submissions remaining in “In Progress” for an extended period with no logs) only started appearing within the past week or so. Prior to that, our notarization requests were completing normally and consistently. Out of curiosity, are you aware of any recent service-side changes or increases in backlog that might explain why established workflows could start hitting this path more frequently? If possible, could you let us know whether anything looks unexpected from the service perspective, or whether this still appears consistent with the in-depth analysis state? Please also let us know if there’s any additional information we can provide to help with that confirmation.
