Hello,

Welcome to Microsoft Q&A!

Could you please tell me what do you mean by “using sideloading method”? How did you sideload the app ? And could you please tell me how you created the app package? Which tool you are using?

Another thing is that have you installed the certificate into the device before you tried to sideload your app? If not, could you please try to install the certificate first and try it again?

Here is a document about how to sideload a UWP package. You could refer to it to get more information about the whole process.

Document: Sideload your app package.

Thank you.

@Shay Wilner , I got that. I suspect that you missed one thing - installing the trusted certificate into the target device. Could you please try to install the certificate first before you sideload your app as I mentioned in my previous reply? Just find the .cer file that packaged in your package folder. Double-click on it and choose local machine- Trusted people for installed location. After that, you could try to install your sideload app.
