Problem on Android device and viewing the project map on any platform

Potentially, but that really looks like a browser problem

Can you try with Firefox?

Yes, I tried with Firefox, Samsung Browser, Google Chrome, and Brave—including in incognito mode on all of them

I investigated further by testing Opera on Android with another browser (including in an incognito tab) and the problem persists. In order to confirm the problem I tested it on an Android phone and the problem is reproducible, considering that my Android phone is rooted, I installed with root a program other than "android photopicker" to select the images and when I send it WebODM and GCP Editor Pro can perfectly identify the metadata of the photos

From what I read on the internet, Android Photopicker automatically changes photo metadata for privacy reasons before sending them. Therefore, in order to allow the use of WebODM on Android, it is necessary to change the trigger from photo to file so that the android photopicker is not called, but the traditional file explorer, or if there is system root privilege, bypass the android photopicker using some other application

In both cases, it is good to document what happened so that future users know what causes it and how to get around it.

Perfect Piero! I'll do it as soon as possible! I even recently identified a problem in viewing maps in WebODM that is not related to the main topic of the post. When I do multiple processes in the same project using GCP in all processes and click to view the project map (so it loads all maps from all process in the view) I can only see the GCP of one of the processes, not all of them. Even in the layer tab, only the GCP of one of the processes is visible.

Below is a screenshot of the layers tab when I view the project map (contains several processes I did)

Below is a screenshot of the map view of a process that has a control point, but which does not appear in the project layer tab.
