@jsebastianms Sorry missed this question.
CFG_STR_CACHE_FILE_PATH can both be a full path or the filename. If this is filename, the directory path is as per the logic defined here.
So for iOS, the default path is /data/local/tmp unless overridden by the application.
Does CFG_STR_CACHE_FILE_PATH need to be a full path or can it just be a file name? I've seen both in the repo. I specifically want to know for iOS. I did see there is a little documentation here: https://github.com/microsoft/cpp_client_telemetry/blob/7d1a165fa4e3a63a21881f45b45bf1fcedb92c5d/docs/Offline-storage-settings.md?plain=1#L13
