I've been using OBD11 Pro for the last year. I accumulate the points by clicking on the ads and have >1200 points now!
I have used the apps to consume points along the way, sometimes it takes a while for the points on the app to catch up, not always but as I say sometimes.
The first thing I would do is go to Google play store, search for OBD11 and you will be given the option to Install, or open/update.
If you have the open option on the right, you most likely have the latest OBD11 version, if it says update... then update your version of the app.
At this point when the app is current, the points total among other things seem to work more smoothly.
