I'm unable to use the PSA crypto methods when OpenThread is enabled on NCS 1.9.1. Linking fails with undefined references to PSA crypto methods.
To reproduce, us the nrf/samples/crypto/aes_cbc example, and add the following to prj.conf:
CONFIG_NETWORKING=y CONFIG_NET_L2_OPENTHREAD=y
Building for the nrf52840dk_nrf52840 yields errors:
