hi guys, I am using the lates updtaed buildbox classic and trying to upload my bundle to the google play store. However I come up with this error: "We've detected this app uses an unsupported version of Play billing. Please upgrade to Billing Library version 4 or newer to publish this app" I know there are a lots of threads on this in forums but couldn't find a single solution to this problem. I remember I had solved this by changing the version to billing settings in android studio but couldn't find it this time. I would appreciate help. I found a thread in which there is a video which is now a private video.
