Land capture wasn't working exclusively due to iOS failing to download the geocoding mappings, a fix for which was released via an in-app update on Oct 27, 9:58 AM.
No releases were made since then.
If the capture started working for you recently then there are only two possible explanations:
1) The in-app update has just reached your device with a massive delay (possibly due to connectivity issues, lack of space, the game not being open long enough or something along those lines).
2) Your device had a local cache of the invalid geocoding maps that has finally expired on its own accord.
In any case, I am glad that this is now resolved!
However, I would be super grateful if you upgraded to iOS 14.2 to see if that helps with the scrolling issue as well.
