To user app crashes on opening,
Please try again with clear data and cache of Yeelight app in android settings or uninstall and install the application again could resolve the issue.
We have found root cause of the issue that we released a beta version 2.3.22 to Google play but it didn’t transform to gold version. If you update to Yeelight 3.0 from version 2.3.22, app will be crashes on opening.
Please don’t worry about version 2.3.20 online, it works well after update.
Thanks for you support！
