Hi @gi395923 ,
I do not think that this is the correct community for this quesiton / (or at least it is not yet)
So far I know
The functionality of the Vuforia SDK is directly supported on the Vuforia Developer portal
The Support portal – the Support center:
https://developer.vuforia.com/support
And the support forums :
https://developer.vuforia.com/forum
In the Forums you can directly report a problem with the Vuforia SDK -> create a new Topic for your issue
So I think this should be the correct area for this particular problem: https://developer.vuforia.com/forum/ar-technical-discussion/android
For Vuforia Engine issues could be reported on the following link /PTC Web Page:
https://developer.vuforia.com/support/contact/cloud
Of course if some community member has experience in this matter is wellcome to help.
