EteSync 2.4.3 for Android - Downloaded >4 GB of background data within a month

[odkr]

I am using EteSync 2.4.3 for Android on FairPhone 4 5G running Linneage OS 20.

I have been using EteSync for years, mostly without issue, but starting last December, I’m reaching or exceeding the data limit of my mobile plan, which is a first. I didn’t think too much of it first, but I just reached my limit for February, so I checked. And it’s EteSync; it downloaded 4.26 GB of data, which accounts for %80 of the data transferred within the last month (see screenshot below).

I had a look at the sync log, but -- at least as far as I can see -- there's nothing unusual there.

Thanks for looking into this.
