I have been working with vuforia and addressables, for a long time and the loading of data and scene has worked for me. My problem is adding a new target.
What I do is create a new image target in the vuforia database.
Then download, Open in unity and update.
If the target was already created before, the changes are updated, but if it is a new target, nothing is updated.
if anyone knows something about it to update the vuforia database please tell me and if you use addressables like me better.
