Should I learn Shahmukhi as a heritage speaker primarily using Gurmukhi?

I grew up speaking Punjabi with my family, but I only read Gurmukhi. My relatives from the Pakistani side of Punjab send me messages in Shahmukhi, and I feel like I'm missing out on half the culture and literature. Is it worth the effort to pick up the Arabic-based script, or will I just get confused switching between the two systems? How do you manage the disconnect between these two scripts while trying to maintain fluency?
