The answer is No. Your settings and configuration will not be changed. However, if you revert to an old version, please be mindful of the issues that will re-appear on your native app and the new updates/features that come with the updated version.
Before using the old version of the BuddyBoss App plugin, please check our release notes so that you can have a better idea of what will be applied to your native app and see the possible issues that might occur.
