Cubasis 2 Compatibility with iPadOS

Hello, is Cubasis 2 compatible with iPadOS 14?

I‘m using the LE 2 as an upgrade version. For 2,5 years I‘ve hadn‘t any problems. Since padOS 14 Cubasis is crashing down several times while I‘m setting the marker to start the track at each point.
Cannot find the reason…

Version 3 is not stable.
So far it‘s not recommended.
