Wingsland z15 not syncing w/m210v1

Anyone have any suggestions? I’ve read the wingsland z15 is compatible with m210 v1, on gimbal 2 with latest firmware. Despite, I can’t get it to gimbal sync with z30 (which is on gimbal 1). Also seems, although crystalsky and pilot app are on latest, it doesn’t show on, flash, sos. Instead shows on and 1.5 hz 3.5 hz, which appear to be flash and sos.
