It worked on another device, thank you.
The average person won't deploy Traccar, so IMO it's not a reasonable response or a position to hold.
Also, for apps development, especially those accessible from the network, Docker has been the standard since years now.
This whole "docker as 2nd/3rd priority" stance is really difficult to understand and IMO hurting the project's popularity.
Find Hub is a personal thing. Each end user would need to have a service deployed against their own Google account. So it's absolutely not the same thing as deploying Traccar server.
Congratulations!
One question: from which server version can I use Traccar Relay? Which Traccar server version is required? Is this APK already backward compatible?
It's not in the official release yet. You need to use the preview.
"Find Hub is a personal thing. Each end user would need to have a service deployed against their own Google account. So it's absolutely not the same thing as deploying Traccar server."
I don't see any way how that answer corresponds to the issue.
There are orders of magnitude more users of Traccar than people hosting Traccar. A single Traccar server can easily have hundreds or even thousands of users.
For technical people Docker is probably better, but for an average person the app is definitely an easier experience.
