So this isn't just an issue of 1.19.21. I've had this issue since November 30, 2021 when the 1.18 update came out. But now it's an issue because I want to transfer my world onto other devices and my world file is stuck on 1.17. I checked the new storage area that they are located in and I tried every YouTube tutorial and I was able to find the file but it was last modified on the 30th of November. My game was always set to external file storage so I don't understand what the problem is.
