I had a look at the battery stats, and apparently the exposure notifications had used 22% of my battery since the last charge.

The last app update I can see what 23rd March, and supposedly the latest update was blocked (https://www.bbc.co.uk/news/technology-56713017) - I wonder if the 23rd March update was waiting to turn something on in the next update, but being blocked the notification is making it go a bit crazy?

Has anyone else noticed this?

The only other thing I can think, is that the PiHole is blocking something, but I can't see anything obvious.
