Sometimes, the 3D tile information is not consistent/as up-to-date as the 2D tile information. However, the same timestamp is given. There is no way to know if the information will match nor how up-to-date the 3D tiles are.

It would be desirable to:
- have newer, updated 3D tiles; or at least be able to request an update;
- have the correct timestamp information for 3D tiles (when was it created?)

Reproducing the issue:
this is an area I know where the information from 2D and 3D tiles do not match and the timestamps are shown as the same:

https://www.google.com/maps/place/R.+Vera+Linhares+de+Andrade,+2011+-+C%C3%B3rrego+Grande,+Florian%C3%B3polis+-+SC,+88034-700/@-27.5986301,-48.4990898,106m/data=!3m1!1e3!4m6!3m5!1s0x95273918808cce8d:0x37b55868335d43bb!8m2!3d-27.5985182!4d-48.498957!16s%2Fg%2F11spnrmwsb?entry=ttu

Switch the location from 3D globe/2D satellite or request it from the API as 3D/2D tiles. Note the timestamp states 2023 for both pictures.

Application get crashed when Recylerview reach at end(last page). Inside GithubRemoteMediator.kt I have set val endOfPaginationReached = page > 2 to allow maximum 2 pages for testing. So, the problem is when I reach at the last page of list, application get crashed as remoteKeys.nextKey is null(as we have set nextKey=null for last page of list).

Do you have a stack trace for the crash you could share?

Offline cache broken How to support caching when application is open without internet connection. currently it is showing retry button. How to show previously loaded data. I have tried to fix this by removing

This might be due to loadStateFlow / listener logic on the PagingDataAdapter which hides / shows UI elements based on load state. You'll want to modify that logic to only listen to remote errors and not the local ones as well.

1. stack for remoteKeys.nextKey gets null

2. I have checked loadStateFlow / listener logic and changed it to listen only remote errors using loadState.mediator.refersh. But still, in offline mode application shows empty list. I have also removed the loadStateFlow / listener but still, it's not working in offline mode. It is not fetching data available in databa.
