AppNana Tips and Tricks: earned video points

I found that after viewing video adds from Appnana's 'Get Nanas' section  'Nana Offers 4 - Videos', the points were not always granted straight away. It was not very inconvenient since I had a work-around: close the AppNana app, remove it from the latest apps cache and then start AppNana app again. Normally my (small) amount of reward points  for viewing the video add would appear.

I noticed that adds by Vungle are apparently handled properly; they instantly give the points as expected after viewing. Ads from Adcolony are never visible instantly; so that's why I used the procedure as described above.

However recently I discovered a quicker shortcut to retrieve my points:
1. watch Appnana's 'Get Nanas' section  'Nana Offers 4 - Videos' and view one or more videos (you have to run them completely to earn your reward).
2. if the shown video is presented by Vungle, your reward points will be present already.
3. If the video provider is another, e.g. Adcolony, just open 'Nana Offers 1 (Recommended)' section, then use your back button (<)  to go back to the 'Get Nanas' menu. Voila! Your reward should pop-up.
