Ratings and reviews

the app is super convenient for moving money between accounts at old second. it has a zell feature and a payment feature that gives constant errors (with no explanation) when I try and send people money.

So far, I have not had any major issues with the app or this bank since the name changed in December 2024. MY only complaint is that I need/would like for the bank to increase the limit amount that can be Zelle. I was trying to pay a business and I had to do it in 3 transactions over 3 days!!! AND once you have Zelle the max($600), that's it for the day. INCREASE THE ZELLE AMOUNT LIMIT, THANK YOU. I have business to take care of.

Latest update is garbage and makes the app unusable. I can't log in anymore. Please fix this.
