Thought I had gotten a bad batch of batteries because no matter what I did, I couldn’t get an AirTag back online after a replacement.
Turns out, the bitter coating seems to be preventing proper contact in the AirTag. Cleaning the battery off with an alcohol swab solved the problem immediately for me and my AirTag came right back online.
Does something like that not just pass right through?
A lot can go wrong, mostly chemical burns or GI obstructions. Since it’s usually little kids that eat them it’s that much easier for it to get lodged somewhere and create problems
