Remember to collect your timed research by watching twitch for 30 minutes, and with your Pokemon trainer club connected to that Twitch account (doesn't need to be connected to pokemon go account, and I wouldn't recommend unless 2FA in PTC)
When you have watched 30 mins you find the drop in twitch settings, so remember to search there if you wont find it in rewards.pokemon.com
Also a small tip: you dont need to go into Go Battle League in the last page, just fight friends/family members account which has cp 10 pokemons, so you won't waste much time chasing win or battling in GBL!
Happy ECTM hunt!
