Paid Pro account lost ownership and access to sheets after March 2026 login update

Question

Hello,

I am posting this publicly because my support case has been open since March 11, 2026 without resolution.

Case:

09052171

My paid Pro account started failing after the March 2026 Smartsheet login/platform changes.

I am currently experiencing:

* Sheets becoming read-only
* Newly created sheets disappearing or failing to save properly
* Loss of access to sheets I own
* The system asking me to request access to files where I appear as the owner
* Communication errors with Smartsheet
* General platform instability

My subscription is still active and paid annually.

At this point, this no longer appears to be a normal support issue, but a possible backend permissions, ownership, or account integrity problem related to the recent login/platform changes.

Has anyone else experienced this behavior after the March 2026 updates?

I urgently need escalation to engineering or account administration.

Thank you.

Hi @julio vulcanus

From this description it sound like perhaps there have been sheets or items created on a different plans in the past. You can check what your default plan is by following the steps in this article:

https://help.smartsheet.com/articles/2483263-change-default-plan

If some of your sheets are showing as View Only, it may be that they were created under a different subscription which has now been cancelled, even if you are on a new subscription. Items are owned by Plans, versus individuals. See:

https://help.smartsheet.com/articles/2483118-asset-ownership-overview

What I would recommend doing is create a copy of the sheet(s) with Save as New. This should ensure the asset has been created in your new, current plan, and that you will have Owner permissions and full editing capabilities.

If this hasn't helped, please do keep following-up with Support as they can look into the back-end of the sheet for you and see if there's something else going on.

Cheers,

Genevieve

What you’re describing definitely sounds bigger than a normal browser or sharing issue. If sheets are becoming read-only, disappearing, or asking the owner to request access, that usually points to something wrong on the backend with account permissions or ownership syncing.

You may also want to ask specifically to:

* Verify sheet ownership integrity
* Re-sync workspace and sharing permissions
* Check migration/login update impact on your account
* Review backend account logs for permission conflicts

Hope they get this resolved soon; if you need any support, let's connect.
