Very high flash memory usage on the BangleJS 2

Hello,

I got an issue with flash memory usage on the BangleJS 2.
The usage increase a lot, first slowly then faster and faster after ~2 weeks it show the "Low memory" error and the storage space left get to less than 3000.
I already made a factory reset and reinstall my apps and the issue is still there.
I just rebooted my watch and it got from a free storage of 5169 to 5045 after the reboot.
I looked at the files on the watch with the web IDE to see if it wasn't an app using all available space and none of the files I can see (some I deleted to check still) can explain this storage usage. Any idea ?
