Barely finished Portal Event Act 2 without potions

Every time there's a portal event, I used to save time and effort by using the potions you get from watching ads well.. But this time, they keep telling me to buy potions with gems 😰 When I did Act 1 on the first day, I got one potion to speed up gathering by watching ads and one potion to get an extra item when merging, and finished it well. Yesterday, I entered Act 2. For the past two days, yesterday and today, they haven't given me potions for free and keep telling me to buy them with gems... Is it because I raised my Dragon Power by over 3,000 in just one day yesterday due to those shiny days? Or is it because I've been using potions too well all this time? They don't seem to give out potions for free anymore. Anyway, trying to play without potions makes me want to earn gems and buy them lol But somehow, I managed to finish it without them. Since I need to finish Act 1 quickly to get additional rush rewards, I wish I could at least get free potions for Act 1 in the next portal event 🤣
