Browser Settings to Check

#

Disable Extensions

Some browser extensions can interfere with Power Apps:

1. Open your browser's extension/add-on manager

#

Enable JavaScript

Power Apps requires JavaScript to function:

1. Go to browser settings

3. Ensure JavaScript is Allowed

#

Check Pop-up Blockers

Authentication and Permissions

Sign Out and Sign Back In

1. Go to powerapps.microsoft.com
2. Click your profile picture → Sign out
3. Clear browser cache
4. Sign back in with your credentials

Check App Permissions

Verify you have the necessary permissions:

1. Contact your app administrator
2. Ensure you're in the correct security groups
3. Verify your license includes Power Apps access

Multi-Factor Authentication Issues

If using MFA:

1. Complete the full authentication process
2. Check for pending MFA prompts
3. Update your authentication methods if needed

Network and Firewall Issues

Corporate Firewall Settings

If you're on a corporate network, ensure these domains are whitelisted:

*.powerapps.com
*.azure.com
*.office365.com
*.microsoftonline.com
*.msecnd.net

Proxy Settings

2. Configure browser proxy settings accordingly

Power Apps Service Issues

Check Service Status

1. Visit the Microsoft 365 Service Health Dashboard
2. Look for Power Apps-related service issues
3. Check the Power Apps Community for reported issues

Regional Service Availability

• Verify Power Apps is available in your region
• Check if your app is deployed in the correct environment

App-Specific Troubleshooting

Large App Performance

If your app is complex or large:

#

Optimize App Performance

1. Reduce Gallery Item Count

   // Instead of loading all records
   Filter(DataSource, Title <> "")
   
   // Load only necessary records
   FirstN(DataSource, 100)
   

2. Use Efficient Formulas

   // Avoid nested LookUp functions
   LookUp(LookUp(Table1, ID = 1).Table2, Status = "Active")
   
   // Use Join or Filter instead
   Filter(Table2, ID in Filter(Table1, ID = 1).Table2IDs && Status = "Active")
   

3. Minimize OnStart Actions
- Move heavy operations to specific screens
- Use lazy loading where possible

Data Connection Issues

#

SharePoint Lists

• Verify list permissions
• Check if list columns have been modified
• Ensure data source connection is still valid
#

SQL Server Connections

• Test connection from Power Apps admin center
• Verify SQL server is accessible
• Check if credentials need updating

Advanced Troubleshooting

Power Apps Admin Center
