up2stream mini DLNA swallowing last 4 sec

when streaming via WiFi using DLNA protocol to my up2stream mini, the last 3-5 seconds of a song are muted.
This happens with android “4STREAM” app but also other apps such as “Hi-Fi Cast”. Songs are stored on my phone.

Is this something that could be fixed? device firmware version 4.6.415145.3, build date 20220427
