My truck received OTA Ford Power-Up # 3.5.4. today also. I, too, received 3.5.3.2 on 2/3/23.Just got the 3.5.4 update notification on my phone. Received 3.5.3.2 on Friday.
Both updates were completed when I was either out for an appointment or at work. Wondering if the LTE signal is too weak at my house, or if it’s just a coincidence.
