Hello! There are a few issues raised here that warrant a bit of clarification so I'll do my best to answer some of these.
Unfortunately not. As part of the rework to loading and saving for FMM24 we had to change the file format for all saved files. This will give us greater felixibility in the future and will also make it easier to maintain compatability should the format of these files change again. I'm sorry for the inconvenience this will cause but we're optiomistic it will be short term pain for long term gain.
This will depend on whether you're playing on Android or iOS. For iOS the changes are minimal. There is now a 'user' folder that contains these files and is essentially partitioned based on your Netflix user account. For Android things are quite a bit different. Saves are stored in the app's internal storage making them inaccessible. This is the reason behind adding the import/export functionality on Android. By using those features you can transfer files to and from the internal location from your device's external storage.
This is an interesting point and something I'll raise with the wider team. Thanks for your feedback!
We're aware of this issue but it is unrelated to the new format changes which are mainly metadata changes rather than changes to the actual file data itself.
