Due to upcoming changes in the root certification of the TLS certificates, the current certificates are cross-signed, to have proper support on older Android devices (4.4-6.0). Due to problems in the cross signing, only the new root CA was recognized, which is not trusted by the older Android devices (4.4-6.0).
