Hello
I have a problem with one of my applications, when a user is trying to access the application and they have changed the default device font size to the max or bigger font size, the
<ion-datetime [preferWheel]="true"></ion-datetime>
glitches and keeps scrolliong the year , month or day.
Here is an open issue about this which mentions two other related issues as well - bug: ion-datetime wheel roll autmaticaly on some androids · Issue #29752 · ionic-team/ionic-framework · GitHub.
As a temporary solution, you could try reducing the text size in the picker. Dynamic Font Scaling is what is making everything bigger.
