default email address not working for signup

[nerocristallo]

I want to use two different flows for signin and signup

I am currently using "email" parameter in signIn method for pre-fill the email address FUIEmailAuth.signIn(withPresenting: rootViewController, email: "[email protected]")

This method runs when I push the signIn button

    func signin() {
              
        self.authUI.tosurl = nil
        self.authUI.privacyPolicyURL = nil
        
        if let rootViewController = self.window?.rootViewController {
            let providerFUIEmailAuth = FUIEmailAuth(authAuthUI: self.authUI, signInMethod: EmailPasswordAuthSignInMethod, forceSameDevice: false, allowNewEmailAccounts: false, requireDisplayName: false, actionCodeSetting: ActionCodeSettings())
            let providers: [FUIAuthProvider] = [
                providerFUIEmailAuth
            ]
            self.authUI.providers = providers
            providerFUIEmailAuth.signIn(withPresenting: rootViewController, email: defaultEmail)
        }
        
    }

and this one runs when I push the signUp button

    func signup() {

         self.authUI.tosurl = URL(string: "https://uptivo.fit/privacy-and-terms-of-use/")!
         self.authUI.privacyPolicyURL = URL(string: "https://uptivo.fit/privacy-and-terms-of-use/")!
         
         if let rootViewController = self.window?.rootViewController {
             let providerFUIEmailAuth = FUIEmailAuth(authAuthUI: self.authUI, signInMethod: EmailPasswordAuthSignInMethod, forceSameDevice: false, allowNewEmailAccounts: true, requireDisplayName: false, actionCodeSetting: ActionCodeSettings())
             let providers: [FUIAuthProvider] = [
                 providerFUIEmailAuth
             ]
             self.authUI.providers = providers
             providerFUIEmailAuth.signIn(withPresenting: rootViewController, email: defaultEmail)
         }
    }

It is working fine for signIn but not for signUp Is it a bug? Is there any other way to pre-fill the signup email address?
