''A beginning'' Dog Tag Dove making a sound but not giving me the Dog Tag

Hi @angry_toast-ofi If memory serves, you should be able to go back, wait for the dove, then jump into it as it flies past. You might want to try posting on the BFEE Discord if that doesn't work, as the people there are usually great at helping with the EEs.

Also, the app is the BF1 Companion. It's discontinued for mobiles now, but you can still access the website at https://companion.battlefield.com/companion/ (N.B. it has limited functionality nowadays).
