Updating a device_tag via the documented API, changed ALL tags to the new value. The proposed change does what it actually is supposed to do.

Hi @MCFurry , Thanks for raising this. Can you provide the exact curl that you used? I'm afraid that the $filter part was incorrectly escaped. For example the following curl (changed to a GET so that there is no hesitation while testing it) returns exactly one tag for me, while I do have more devices with the same & other tags.

curl -X GET "https://api.balena-cloud.com/v6/device_tag?\$filter=(tag_key%20eq%20'stats.last_application_start')%20and%20(device%20eq%2012506355)" -H  "Content-Type: application/json"  -H "Authorization: Bearer <...>"
