So basically i started the quest to get the garchompite and as soon as i arrived at sendoff spring, i defeated the tourist. Now what i have to do is win the battle with cynthia but the battle doesn't start. I went there at 4-5 am with a full lv.100 team, a max evs and happiness garchomp and obviously a pokemon with rock climb but cynthia keeps saying this same thing and won't battle me. Can someone help me it's been 2 days since i'm trying to get the mega stone. I also met some other people there and they are having my same issue ancd cannot battle Cynthia.
Garchomp i am using is on OT AND have attack 25+
still facing same issue
