Fix Power Apps Screens Not Loading or Running Formulas
Question details
The user needs to resolve an issue where custom Microsoft Power Apps screens fail to load, formulas do not execute, or control sizes are distorted.
- Product
- Microsoft Power Apps
- Device & OS
- not provided
- Scenario
- Accessing or running a custom Power App after a recent app, browser, or platform update.
- Observed behavior
- Screens fail to load properly, formulas tied to the OnVisible property do not trigger, and control dimensions appear incorrect.
Verify your internet connection and ensure your web browser is updated to the latest version, or try an incognito window to rule out caching issues.
Verify App Settings and Scope of the Issue
Check if the issue is isolated to your specific account, device, or app before escalating.
Before escalating the issue to administration, it is important to determine whether the problem is localized to a specific user, a specific screen, or the entire app environment.
Ask colleagues if they can successfully load the app and run the formulas to see if the issue is user-specific.
Open the app in Power Apps Studio and verify that your OnVisible formulas and control properties contain no syntax errors.
Navigate through the app to document exactly how many screens are failing to load or displaying incorrect dimensions.
Contact Microsoft 365 Administrator for Support
If the issue affects the entire app or tenant, escalate the problem to Microsoft Support.

Frequently Asked Questions
Why is my Power Apps OnVisible formula not triggering?
This can happen due to recent platform updates, caching issues in your web browser, or syntax errors within the formula itself. Reviewing the formula in Power Apps Studio is the best first step.
How do I report a tenant-wide Power Apps issue?
Tenant-wide issues must be reported by an authorized Microsoft 365 administrator. Provide them with detailed, redacted screenshots so they can submit a support ticket via the Microsoft 365 admin center.
Can browser extensions cause Power Apps screens not to load?
Yes, certain ad blockers or privacy extensions can interfere with Power Apps scripts. Try opening the app in an Incognito or Private browsing window to rule out extension conflicts.
