I created a release group with a version number of 156 and added four merchants. I had to apply an update and created another APK that was version 159. I removed version 156 and added version 159. According to the instructions for release groups in the documentations, I believe that the merchants should have received version 159 within a few days. But five days had passed and they still had not received the update.
Do I have to create a new release group for each individual APK version So the merchant receives it within the release cycle?
