Power Apps and Power Automate Old Designer Enforcer is a Chrome extension designed to modify the user experience in Power Apps and Power Automate by enforcing the use of the old designer interface. This unofficial tool automatically appends 'v3=false' to the URLs of cloudflows, allowing users to retain the previous design they are accustomed to.

Key features include its ability to work seamlessly in the background without requiring user intervention, making it a convenient solution for developers who prefer the older interface. However, it is important to note that this extension is not affiliated with Microsoft, and users should exercise caution as it may affect the functionality of Power Apps and Power Automate. The extension is available for free and is intended for users looking to maintain their workflow preferences.
