Tried with a cleaned new battery. It beeps when I put the battery in, that is it. When I scan for unknown objects, I get shown an air tag, but it doesn't tell me anything about it. So probably I should just remove the battery - I must have gone through a heap of them debugging this - and just smash it.
Oh yeah totally, that “feature” of a Duracell cr2032 battery screwed me over in that exact case. They just don’t work at all with an AirTag (battery bought from afaik reputable supplier, Home Depot).
Switched to Energizer cr2032 and it’s been great.
This is the Cloudflare VPN they announced back in April.
Apologies for the title. I noticed the app update, couldn’t find a blog post or a news article to post instead so I used the first line of the update description.
The first time I replaced my AirTag batteries I had to remove some of the coating or it wouldn’t power the AirTag.
