OK, so the DJI update server seems to be working again. However, I have two of my three batteries on 22.214.171.124 firmware, and the other is on 126.96.36.199 firmware. In the update screen the Assistant (V3.8) tells me there are no updates for the battery. And when I deliberately click the battery link it opens up the second window which also tells me there are no updates. But there obviously is an update, and I think I need it because these two batteries report "Invalid Battery" errors a lot. Any thoughts?
