QFIELDSYNC sync problems

[Nemo1970]

Good morning everyone,
I've been using QFIELD cloud and QFILED SYNC since January of this year to synchronize survey data between field crews and the office.

For some weeks now I've had a problem (in all projects, both old and those created now) that didn't appear before:

1. The field team use the app on their device updating the data, at the end of the day send the data to the cloud;

2. From the office, through the QField plugin on QGIS I perform a sync, the message appears "Some of the files on QFieldCloud differ from the files stored in the local project directory", I choose to download the data from the cloud.

3. The program downloads the data, at this point the files present locally are the same as those present on the cloud.

4. Before a few days ago, if I synced again, the program showed me a message that the local data was the same as the cloud data and there were no files to sync.

5. now however whenever i sync (after just running it) the program keeps giving me the above message, and no matter how many times i sync, it gives it to me indefinitely.

I use QGIS 3.30.2-'s-Hertogenbosch
while the QFIELDSYNC plugin v4.5.0
the project consists of .gpkg files and images,
the message proposes it to me only for the gpkg and for the project files but NOT for the images.

What I have noticed is that every time I synchronize the last modification date of the files it is changed by setting it with the current date and time.

Anyone have my same problem? Thanks for any help you can give me.
