Conquest pass plus unable to defeat enemies node one

I purchased conquest plus pas today. On node one sector one on normal difficulty I cannot defeat any enemy team, not fold path nor standard. I’ve used GL teams, R10 SLKR and while my tea. Takes all the enemy’s health down to one red bar, they cannot be killed and time runs out. I’ve tried several teams with the same outcome. Unable to defeat enemies on first node on normal with high powered gl teams. Feels like I’ve wasted money buying the conquest pass plus if I can’t make any progress at all. Have started and restarted game many times, same issue.
