We have a daily export of some data, that generates a json file, writes it to a storage ccount/container which is then mounted into a linux (Ubuntu) VM in Azure using blobfuse v2.

The folder which contains the file is updated, but the file is not.

azureuser@myvm:/datadrive/blobstorage$ ls -lah
total o
drwxr-x---2 root root 4.0K Mar 19 22:30 INGEST
drwxr-x--- 2 root root 4.0K Mar 19 15:21 export 
azureuser@myvm:/datadrive/blobstorage/INGEST$ ls -lah
total 0
-rw-r----- 1 root root 4.2M Mar 19 14:44 fpl.json
- rw-r-----1 root root 33 Mar 19 15:32 testcontent.txt

Note that the tiemstamp on the INGEST folder is newer, then the timestamps of the files inside the INGEST folder. The files were updated at 22:30.

I have already tried removing the caching, setting the caching values to 1 second.
