So easy to navigate the app as well ! ### 1/5 — Broken deposit app *2026-08-01, version 3.36.0* You have broken my ability to deposit into the right account. Sigh. ### 1/5 — Depositing checks *2026-07-12, version 3.35.1* Your app is SO DIFFICULT!! Almost every time I have to try 2 or 3 times. Way too sensitive. My other banks don’t give me this issue ### 5/5 — Deposit *2026-06-24, version 3.35.1* It was hard getting the correct photo for the deposit. Ask me numerous times to write old second national bank mobile deposit only. ### 2/5 — Update messed it up *2026-06-23, version 3.35.1* Won’t open at all now after last update ### 2/5 — Limits *2026-06-17, version 3.35.1* $5k daily limit. Not cool. Should be a percentage. IE 15% of total savings = daily limit ### 1/5 — Mobile deposit phasing is ridiculous *2026-06-10, version 3.35.0* Check deposit feature is terrible ### 4/5 — Great except for remote dep issue *2026-06-09, version 3.34.1* I like the capability of the app to access info and to execute transactions. I do not like how remote deposits are rejected because I supposedly did not write “Mobile Deposit Only Old Second” on the back. Except I did, in big block printing. I make the letters thicker and it usually helps. A couple of times I have had to strike thru the original and rewrote it much lower on the check. I really wish they would fix this. ## Frequently asked questions about O2 Digital Banking ### What does O2 Digital Banking do?
