Hello,
Two of our SG350--28MP switches are connected by two cables.
We created a LAG for two switchports on both switches.
The LAG functions until we restart one of the switches.
The LAG link is down after the restart.
When we unplug and replug the two LAG member copper cables, the LAG link comes up.
Both SG350-28MP switches are on firmware 2.5.8.15
I already followed the ticket https://community.cisco.com/t5/small-business-switches/sg350xg-to-sg350-lag-not-up-after-restart/td-p/4179343
It doesn't helped.
Any advise to resolve this?

what is the config on that ports, make sure you disable any smartport config on that ports ?
what is the case if only 1 link, is this stay all the time up ? how about spanning tree ?
