Place caret within words to make correction❓

Hi,

we have build an android and iOS-app and have implemented the editor.js

We are facing the problem, that we are not able to place the caret on some position within the text - i.e. to make some correction in spellings of some previous words.

On our web-App it is working fine, but on the apps not.

Do you have an idea, why it is not working on app?

Thank you und best regards,
Sebastian
