Seadroid upload in real time instead when switching network


I observed Seadroid upload content only when I switching network (4G/5G to Wifi --> Data upload only in Wifi tick).
In other words, when I take pictures in my house connected to the Wifi, pictures are not sent in real time.

Solution 1: refresh manually to send picture on the server
Solution 2: do nothing, go outside and when I come back to my house, finally pictures will be sent to the server.

Seadroid 2.2.34
Xiaomi 9 SE Global / MUI 12.0.4 / Android 10
Server 7.1.4
Debian 10 / 64 Bits

Thank you.
