21 Infotainment V155 Update

[SEBFL]

Went to the dealer today and requested that they preform the V155 update, When I go into the menu to the about screen it shows the March 2020 version but below under the update history nothing is shown to confirm the update has been preformed. Should the V155 update appear under history. 

Thanks

Did the dealer do the V155 under warranty? I have a 20 that will not connect consistently to CarPlay or Bluetooth. I know V155 is supposed to be for 21s but I asked about the update and was told it would be $145. I contacted GM and they confirmed. 
 

Another dealer tried another update that didn’t make any changes and has since told me about TSB 21-NA-145. Anyone know anything about that one?

I asked for it but I have no way of knowing if it was done as it does not appear in the update history. That is my question. I suspect that they did not do it.

2021 has V153 no issues

Mine is an early 21 with the old firmware  I assume the V155 will bring me up to date like yours

My truck is loaded with V153 could that be the issue?

V155 is supposed to solve a lot of issues.

This is the bulletin from GM  It's headed Corvette but applies to all the other brands listed. I gave it to my dealer and they are clueless. Hope you all have better success.

V155 update just got pushed to my truck over the air today.  It's a '21 2500HD, bought at the end of January.

This was pushed to my truck OTA.  It does show up in the Update History.

Wonder why they are pushing an outdated update? Do they need to be updated to each version first and then updated to the next.
