Watermark doesn't go if 2 apps from same publisher

We purchased a premium license of Radaee's PDF library that we used to remove the watermark on the rendered PDF images.

But what we noticed is that if there are 2 apps from the same publisher the watermark doesn't go if both the apps are installed on the device (works fine if only our reader app is installed)

The reason for this could lie in the way the radaee library is retrieving the key for the app using this call.
Windows.Phone.Management.Deployment.InstallationManager.FindPackagesForCurrentPublisher().First().Id.ProductId

In our case, we have 2 apps from the same publisher, and if the first app is installed then the above code always returns the product id of the other app, and hence our PDFGlobal.ActiveLicense() call fails
does any one know of a way in which this can be fixed from the app's side?

Soon we will release a fix.
Thank you for the bug submission.

Have you fix this? I'm still getting this problem with more then one application on the phone. I'm using library for Windows Phone 8.0.

Dear user, we fixed the wrong behavior on 8.1 and 10 version.
On 8.0 some of the required API wasn't available.
I should invite you to get in touch with sales team through support area: they will support you generating proper keys to avoid the bug.

Are you sure?
You are using: Windows.Phone.Management.Deployment.InstallationManager.FindPackagesForCurrentPublisher().First().Id.ProductId
But you should use: Windows.ApplicationModel.Store.CurrentApp.AppId and this is available in Windows Phone 8.0 msdn.microsoft.com/en-us/library/windows...sharp#code-snippet-1

Win8.0 was lacking a lot of needed API to improve the overall functionalities.
That bug was left opened and the Win8.0 support left when MS forced the upgrade to Win8.1.

Sales team will help you generating the proper key for your applications.
