Yes, this should be possible depending on how your sheets are set up. If you go to Sign-up Sheets in the admin, find the sheet you want and click on the Manage Sign-ups link. Here you should find the sign-ups for the sheets even after they have passed.
If you are still not seeing sign-ups here, you should verify you do not have Auto-Clear configured for this sheet. You would find the global setting to enable this under Sign-up Sheets > Settings > Sign-up Sheet > Allow Auto-Clearing Sign-ups Per Sheet. You then configure the schedule when you edit each sheet under the Advanced Setting > Auto-clear Schedule. If the global setting is enabled and you have a schedule set on the sheet then your sign-ups would have been removed by this feature.
If this still doesn’t solve your issue, please open a direct private ticket and provide your “Site Information” so I can better help debug the issue. You can do this by going to the Sign-up Sheets Support Contact Form and make sure to follow the steps for the Site Information on that form.
If you have any other questions, don’t hesitate to reach out. Thanks!
