We are investigating this issue right now. This seems to be a non-isolated report. I will post updates here as I receive them.
Apologies for the inconvenience this issue may cause.
11:15am CST update: We have raised this with the product group and have engaged the right resources for investigation. I will update again as I receive more updates.
12:05pm CST update: the product team is still investigating this issue. There will be a Service Health update posted shortly as well.
2:15pm CST update: we've restarted some services and responses should now slowly start flowing in. We do not expect missed responses to be processes by Flow.
Final update 3:00pm CST: All Microsoft Forms responses should flow into Microsoft Power Automate successfully now. Please follow SHD# FL228460 in the M365 Service Health Dashboard for a full RCA in the next few days.
For users with missed Forms responses, here is one possible way to processes these responses:
1. Duplicate the original flow;
2. Replace the trigger with "Manually trigger a flow", add a number input;
3. In "Get response details" action, replace the field in "ResponseId" with the number input of above trigger, and click "Save".
4. Then click "Run". In the "ResponseId" field, you can enter the ID of the responses which didn't trigger original flow.
5. The response ID can be found on form's "Responses" page, via exported Excel, or click "View results" button.
