My MG4 Trophy LR went in to get a Warranty Service for the undertray yesterday and I asked them to look at some software issues:
1. Bluetooth requesting pairing once every couple of days
2.  LKA over zealous.
3.  ACC slows excessively on bends.
I was rather nervous as the garage insisted on me pre-authorizing payment for investigations just in case these weren't warranty issues but in the end I wasn't charged for anything and got the following answers:
1. A USB update was applied for the telephony/bluetooth issue
2. "You have it set to most aggressive level that is the problem"
3. "It is supposed to slow on bends"
Today I went to compare the SW versions and found the following (changes in bold) but could do with a little input on interpreting this...
| Module | Old | New | 
| VR | 4C051 | 1.0.0_EH32_SOP_2407251341 | 
| T-BOX MCU | SNMKP21E32 | SNMKP21E32 | 
| T-BOX Modem | 1.02.001.r02 | 1.02.001.r02 | 
| T-BOX MPU | SNAKP21E32 | SNAKP21E32 | 
| T-BOX BT | BTM010SACwa21019 | BTM010SACwa21019 | 
| DSP | 1400000000 | 1400000000 | 
| FCIM MCU | 68.4.3.0 | 68.4.7.0 | 
| FCIM MPU | SWI68-29958-1300R59 | SWI68-29958-1300R63 | 
| FCIM App Integration | 4C051 | 1.0.0_EH32_SOP_2407251341 | 
| FCIM WLAN firmware | 0x8a11 | 0x8a11 | 
| FCIM Bluetooth firmware | 20191129181225a | 20191129181225a | 
| Map Navigation |  | 6.2.60.1.46507-P | 
 
So I can see they have upgraded the infotainment from R59 to R63.  Have they done anything else?
If yes, will it help with the BT issue? [I think the above tells me they didn't update the TBOX so probably not]
 I note the VR version string is both changed and a different format what does this mean?
