Jumper T8SG V2 plus can't bind with Frysky_D/X

hello,
I found this issues my New Jumper t8sgV2+ already update with latest nighty builds firmware :

deviation-t8sg_v2_plus-v5.0.0-ccc06d0

Im using FC board CrazybeeF3 Frysky version with latest firmware betaflight_3.3.3_CRAZYBEEF3FR (Stable)

i can't bind this FC board with my jumper t8sgV2+ but its work fine with Flysky version (AFHDS2A) with my another FC board CrazybeeF3 Flysky version

I already try to set up step by step for Freq-coarse / Freq fine from -40 to 40 but it never get bind

what do i miss?
is there any suggestions?, maybe Tx setup is wrong?

thanks for any advice

From the info on this page the correct deviation protocol is Frsky.
Leave Freq-Coarse at 0.
Try binding with Freq-Fine all the way from -127 to +127 in steps of 10.

On the page linked above there is a link to this betaflight change discussing issues with Frsky on the crazybee, though not with binding. Looks like a fix will be in betaflight 3.4.

Don't know if this will help but here re the settings I use for my Devo 10 fitted with 4in1 module using FrSky receivers

D8 Mode = -50 Fine
V8 Mode = -47 Fine
X Mode FCC = -61 Fine
