r9mm & r9m F.Port/smartport... HELP!!

Alright before I even get started, heres the equipment i'm struggling with:
Mamba F722s: https://www.diatone.us/products/mamba-f722s-stack
r9mm: https://www.frsky-rc.com/product/r9-mm/
r9m: https://www.frsky-rc.com/product/r9m/
My QX7 is up to date as well. Same with OpenTX.
I have also rest all settings on my Mamba FC to ensure I didn't turn something on or off that I shouldn't have.

So I've been battling this receiver/transmitter/f7 board for a while.
I have tried every combination I can think of trying to get F.Port to work on UART2 (TX2).
I have tried FLEX firmware and FCC firmware updates on both modules and with each firmware I've even tried outputting from the inverted S.port pin on the receiver to TX2.
I have ALSO tried running the F.Port wire to every other unused UART on the board....

I've even given up on F.port and figured I would just run SBUS. when I run SBUS I get stick movement on Betaflight, however when I link the smartport pin to TX2 and resource serial_tx 11 to the TX2 pad (A02) I'm not seeing any new sensors on my QX7.
Also worth mentioning, after every firmware update I re-bind the transmitter.

I am at a loss.
Is there something i'm missing with the r9m or a setting on the qx7???

FPort is the latest RC serial protocol that brings a few improvements over the existing RX and telemetry protocols. This tutorial will explain the advantages of FPort, and how to set it up on Betaflight flight controllers for your mini quad.

Thank ya! I've been following his guide and still no luck.

Tonight I'm going to try re-flashing the r9m FLEX firmware because I was flashing the r9m2019 version firmware to the module and i'm hopeful that will fix the issue. Since I bought the r9m in late 2019, naturally, I figured I had the 2019 version but i actually have the "original" r9m module.. smh.

Getting to the point where i want to just trade everything for crossfire

+1 for crossfire. Never tried the r9 but crossfire was very easy to use, I was surprised when the module itself actually updated the firmware on the reciever and started working, no problem.

Update on this:
Tried re-flashing the F7 board - No luck
Tried deleting the model and making a new model from scratch on teh QX7 - No luck
Tried turning half duplex & inverted rx on & off - no luck
Tried another Mamba F722s board - no luck

all in all, I gave up with figuring out F.Port. I've been messing with settings for more than a week. I was able to get SBUS/smartport working perfectly fine after flashing the r9mm to regular FLEX firmware. Took me about 2 minutes to set up. Not worth the headache of figuring out FrSkys mess lol.

Since I have another F722 and r9mm, I'll continue to play with this combo and try to figure it out in my free time.
I'll update this thread if I ever get it fixed before I switch to TBS lol.
