Issue - Image Anchor not working with any Android

Hello,
I am currently teaching an introductory course on virtual reality using Adobe Aero. However, all the students in my class who have an Android smartphone are encountering a bug.

When using an Anchor Image, the application never manages to recognize the image. I have tried various types of images, always following Adobe Aero's recommendations and those from the community.

This issue is also reproducible on my own Android device.

Thank you in advance for your help!

Guillaume
