Almost never getting offer for 2x gold video

As the title says… I did 10 raids this morning didn’t get the offer even once.

Playing on android from Norway 

Why?

From my observations: it seems, that you don’t get them, when you already used a lot of ads, e.g. farm boosts, free chest, duration reduction …
But when you can get them, they only offer it for small amounts of gold. Flare, please reconsider this. Why should i waste those limited ads
for 100-300k gold? When i have a sifnificant amount of loot (1+ million), it never shows up.
