3EM repeated records and missing records in log files

I'm trying to do an analysis using my stored data.

I've been having problems downloading 3em log files. I keep getting incomplete values. When incomplete, the whole day is missing.
I also get repeated values.
In both cases when repeated, or missing, records correspond to the whole day. By whole day I mean the 144 records.

Anyone out there can confirm having this issue or not please?
Two of people I know that have the 3em are having the same problem. Both own then 3em for more than a year.

Another thing that I noticed is that when there is missing records you find in their place repeated ones.
I have an open ticket with shelly support and I'm getting a response that this has to do with "internet issues".

Not sure what the internet has got to do with this. I think I'm connecting to the device locally. My wifi signal appears as "Excellent" . Both PC and 3em are less than a meter a way from the AP.

Thanks in advance to anyone who responds.

Technical support has confirmed they can reproduce the problem but hasn't given me a date for the fix.
I wonder how other people are getting by with a device that not only shuffles the information but takes some out. Its a night mare to get any analysis done!
