No video ads for training?

The new training bonuses made it more difficult, but ok, I can live with that. Sometimes I must use greens or go into game with not fully rested players, but it still is ok. But maybe Noredus think we are still not spending enough? Why the hell I can't watch video ads for doubling training bonuses? It happened to me several times in past weeks and this morning again - I watched only one video ad for training, but then the "2x" button was gone. No, I haven't watched ads to get greens or other packs for a long time. And yes, if I go to the packs screen, I still can watch videos to get packs. So why the same ads can't be used for trainings? Are Nordeus really trying to get rid of long-time loyal players? It seems so...
