IS UNION BANK SCC WORTH IT?

Is UB Secured Credit Card worth it? I applied on April 16th. It’s already 12 banking days and still no update of approval or if the card is processing. The 20k deposit is still in my savings acc and was not hold out yet. I’ve read stories from here na once mag mature (mag 1yr) ang scc with UB, they won’t convert it to regular cc so the NAFFL offer is no use. Is this true? Should I not push the application and go with BPI/Metrobank SCC instead?

This SCC is supposed to be my first cc to build my credit score. Unfortunately, I’m starting to contemplate if I made the right decision.
