DJay crashes on Android

The new version 2.3 of djay crashes very often (every 10 to 20 minutes) when using the automix function on my tablet Samsung Galaxy S 10.5 with Android version 6.0.1. Sometimes the tablet even does a reboot. So the Software can no longer be used by me.
The older Version 2.2.8 of dejay was much more stable and crashed only every 3 or 4 hours.

How can I downgrade to the older Version again until the Problems are solved?

No Support?
