Cannot load experiment

[detector]

I've generated an experiment via phyphox-editor. Works perfectly fine on my mobile phone (Android 13/Bluetooth 5.0). When trying to load that same experiment on an much older tablet (Android 5.01/Bluetooth 4.0) the loading stops with error message "XML-error in line 1. Expected a quoted string (Position: DOCDECL @ 1:50 in java.io.buffered reader @168F3801)." What's wrong here?

Could you please share the experiment source here?

Do both devices run the same phyphox version: tap the encircled “i” in the menu and “Device Info”? (On iOS, I would get an error message complaining about an unsupported file format version, however, I am not so sure about Android)

It might be a problem of the ancient Android system and the website certificate of our server. Could you try open it from a self-hosted website –the QR code just needs to be a link and if you use phyphox:// rather than http[s]:// it should work “out of the box”– or from storage?
