Screen Flickering and driver side cluster problems

I had what I thought was the MCU replaced in June for a huge bubble in the screen. The screen started flickering this week. I contacted Tesla as my Driver side cluster is also taking forever to turn on. I am told the MCU needs to be replaced and infotainment upgraded. When the screen was fixed wasn't the MCU replaced then? Need some advice. I feel like the car is beginning to fall apart. So much time is going into fixing all these little issues

It’s been noted here that older version cars can’t opt in for the daughter board fix as the MCU is not compatible, they need full new unit.
Everyone’s getting conflicting information. From what I’ve been told is just requires the upgrade to LTE and a new jumper. My car 12/14 came with both of those things both standard. I read in a thread that it didn’t start until 12/15 but then I’m left wondering why my car had it at delivery? The LTE is only an extra $150 upgrade if you have 3g currently. It’s worth it to ask Tesla because $650 is cheaper than $1500 for new mcu1 or $2300 or mcu2
