@AKtheLaw Hey there, as a starting note Welcome to the community of NBALM players determined to help each other and bring about great discussions.
Secondly, coming to your query , as a player who has been through the same trauma and frustration back in the day of no available ads, I do understand it's really disheartening to know getting a better reward relies on something that isn't always achievable for only a few players.
Now I've been in the situation you are rn, and your understanding of the ads system is a little flawed, so let me walk you through it.
After you watch an ad, another ad usually tales about 2 minutes to pop up. Now ads are common for all the rewards in all tabs including stamina. So ad as an entity are same, the rewards depends upon which tab you went to watch it. Now i see your problem is a typical problem i face from day to day, as you have 1 ad watched and then suddenly the ad system snaps and doesn't give more ads. I assure you, from all such cases of consumers I've seen, simple workarounds like reinstalling(only if logged in through play games/gamecentre/Facebook and NOT on guest mode) the game, logging in and out(remember to do it several times and wait for around 2 minutes or play one or two events to see if the ads are available after the 3rd or 4th log in) and restarting your device works. Also keep in mind to not exit the app or switch apps in the middle of the game or the ad, it somehow leads to unavailability of ads. Also sometimes it so happens that the ads reload after around 18 to 20 hours of the last ad you watched(in the previous session not the running session)
Please try the logging in and out a lot of times, ive had to do it about 21 times a day, its strenous but if successful, it can give you better rewards.
Thirdly, it's not you, many people facing unavailability of ads are really unsatisfied by the fact that the game develops haven't made changes to the as system to benefit all. The community team checks this forum and the person pertaining specifically to this forum is currently unavailable due to some problems(
@EA_Blueberry ) But I'll make sure I have another Community Manager look into this matter and try to change the current situation at the earliest.
