Hello, Elle,
Yes, the drop in temperature is quite noticeable this night.
I agree ads are bothersome, Elle, but for every problem there is a solution!
You do not need to install an adblocker.
My solution is to download a browser with a built in adblocker.
I use "Brave" browser on my tablet instead of Chrome.
I think it is faster than Chrome and has no ads, and it's free.
There are several browsers with built in adblock, including one browser by Adblock themselves.
Have a look in Google Play Store?
My books added, are "The Last Hillwalker" by John Burns, and "Farthest North" by Fridtjof Nansen.
My wee list is growing!
