i.MX 8M Plus VSS pins

Hi everyone,
Are all the VSS pins on the component connected internally? If there is a problem with the assembly of one of the pins, could this affect the function of the component? I ask this because the vendor of the PCBA reported an assembly problem with the AJ1 pin that is connected to VSS. The question is, is it necessary to rework or can it be given up because all the pins of VSS are connected to each other internally and AJ1 is not really responsible for a certain block? pictures attached.
Thanks for the helpers!

Hi @DanielDs,

I hope you are doing well.

All VSS pins are internally connected to each other. However, it is highly recommended to connect all VSS pins to the GND since there may be the possibility of a long current return path due to not connecting the VSS pin.

Thanks & Regards,
