I beta test the apps and FW and occasionally run into issues. However, there currently is no Beta App for Android. I have 2.26.22. However, Sign-up for the Beta by going here: Become a Beta Tester. Once you sign-up, you can start the App, go to Account, About, then Beta Program. From there you click the edit at the Top Right and check the boxes of the devices you want to test the FW on. Make sure you save and back out.
Once you selected the Items you wish to beta test, go back to account then Firmware Updates and you should see it there. Otherwise, go to the actual device and you should be prompted with a FW update.
Note, since there is no Beta for Android, you may have to Uninstall and then Reinstall after you signed up for the Beta App.
As a side note, you can Join and Leave the Beta Program as you wish. But the FW updates will not automatically roll back. you will need to do a manual roll back or wait until the next Production FW update is available.
