In Lora-App-Server version 2.5.1, when I have a populated Application, the button “Delete” delete all devices in an application. I think this is a too easy manner to delete all devices in one time. May cause errors in case of human mistake. One suggestion is to double-confirm the deletion of an application with more than one device activated.
As i am new to git/github i wanted to try the pull-request. i did this with your message provided.
Hopefully is all good - if not, please let me know, then i can learn from my error
