Square Online missing features

[BoMA]

I have a 'Promote Grow' plan. I lost my 'subscription' functionality when I had to move from PayPal to Square payment processing. Can you please tell me how I can get 'subscription' functionality without moving to Square Online. When I tried the Square Online free trial, I found that a critical app, 'Paid Members App' doesn't work with Square Online. I only had 22 customers when I was in Square Online. Some of my site items didn't show up on Square Online and I didn't see any marketing history on Square Online. Bottom line - Square Online doesn't seem to bee feature complete yet and I not longer have 'subscription' functionality because I was forced to change from PayPal processing to Square processing.
