You don’t have permissions to these records or something may be wrong with the site map. Contact your Dynamics 365 administrator.If you are the administrator, you can go to the solutions page and import a different solution.
Is this a temporary issue? The permissions didn't change, nothing actually changed, the page is just.. gone?
That's incredibly frustrating, especially when you know you saved it properly. This is unfortunately a known issue that pops up from time to time in Power Apps. Here are some things to try:
Immediate checks:
First, don't panic and don't try to recreate anything yet. The page is likely still there — it's usually a sync/cache issue rather than actual data loss.
Clear your browser cache and cookies for the Power Apps domain, then reopen the app in an incognito/private window. Sometimes the editor caches a stale version that conflicts with the published version.
Check the app version history. Go to Power Apps portal → Apps → find your app → click the three dots → Details → Versions. You should see all your saved versions listed there. If your recent saves show up, the data isn't gone — it's a rendering/loading issue. Try restoring the most recent version.
Check the solution layer. If this app is inside a Dataverse solution, go to the solution → look for your app → check if the page/screen is listed as a component. Sometimes solution imports or updates can overwrite customizations.
If it's a Model-driven app:
That error message about "site map" and "Dynamics 365" suggests this might be a model-driven app. If so:
If it's a Canvas app:
Last resort options:
About the error itself:
The "don't have permissions to these records" message is often misleading — it can appear when the app tries to reference a component that it can't find (like your missing page), not necessarily because of an actual permissions change. So the error is likely a symptom of the missing page, not a separate problem.
This kind of thing usually resolves with a version restore. Definitely check that first before attempting to rebuild anything.
