Cache values in power canvas fields

Junk cache values are visible in canvas apps fields. I can clear them by cleaning the History in the browser.
But can't ask user to do every time.How to avoid these caching values in these fields.

    Cache values in power canvas fields
    This is very similar to an issue I am having.  When you submit a form and then start a new form all fields appear empty...but if you do not add anything into that field before submitting the second form entry then it submits the previous form's field data into the empty field.  ResetForm and NewForm do not seem to affect this in any way.  The only way to stop the data re-submitting is to refresh the browser or PowerApps App.
     
    There is no option for autofill on my browser, and I have disabled SaveData/LoadData/ClearData in the settings of the app.

    Cache values in power canvas fields
    By default, Power Apps doesn't cache the values in canvas app fields.
     
    On the basis that you can clear them by clearing the browser history, there are only 2 things I can think of. First, is that your app has been coded to cache the values locally with the SaveData/LoadData functions.
     
    The second is that what you're seeing is auto complete feature of Edge or your web browser. If this is the case, this is not something that we can control from Power Apps. The user can click the X icon in the auto complete to bring up the option to not auto complete, or to modify this behaviour in the settings. 
     
     
    If none of these solve your problem, perhaps you could provide more details as to what you're seeing and how your app is put together.

    hey
     
    i am also not aware of this problem and have never faced it. what exactly do you mean? what you can do and see if that helpd to use the Reset() function in the app onstart and reset the input controls and or forms (or whatever you are using) and see if that solves the problem

    maybe you are using some default values in your controls? have u checked this aswell?
     
     
    if my answer helped please mark as verified answer ;) thanks

    Hi
     
    I am unaware of this. Are you saying someone closes and app, restarts it and data is filled into the controls?
     
    If so you need to get a bug logged at the Microsoft side.
