(1) Could be SimBrief - Dispatch or maybe even something like…
(2) MSFS normally uses the latest AIRAC cycle of navdata (e.g. 2303 March 2023), but can sometimes be a little out of date depending on if they release it with some other content / update or not on time. I use a Navigraph subscription (as 3rd party aircraft tend to use their own data format, plus it has some fixes in it that are super helpful), but I think MSFS base data might be behind at the moment? I don’t remember the 2303 AIRAC for MSFS as yet, but could of missed it? Even if it is 2301, it will still be relatively up to date.
