Okay I have just tried all of your tips and tricks, but to no use

Greens have since the last update been a hit and a miss, where it just searched and searched for available videos but ended up with nothing, BUT, yesterday and today it doesn't even search! it goes straight to "no reward videos available" instantly. Now I have tried:
clearing cache = nothing
trying from Facebook Gameroom on the computer = nothing
reinstalling app = nothing
farming greens from training as you suggested = nothing
Installing v6.7 = nothing

It's really depressing as I've bought 4 new 18yo at the start of the season and am used to farm 25 greens a day, but the last 10-15 days I have maybe been able to farm 5-7 a day and now the last two days, nothing. not searching for videos, just stating that there are none and I should check again later.. I check 30 times a day and nothing.

What can I do? -Tried writing Nordeus support a week ago, but they couldn't help
