*2026-02-13, version 5.7.0*

Congratulations on the new update. (12/2/2026)

A little hiccup is; Rows 3 and beyond are not clickable.

neither can i click the “•••”, which i think is the expand button.

**Developer response:** Hi,

Please reach out to us at info@stinu.app so we can have a look at your case. We don't offer a monthly subscription, so your case looks odd and needs clarification. Please make sure to install STINU only through the AppStore to ensure that you are using the official app.
