EPUB highlighting/selecting text bug specific to iOS mobile phones

edited April 10, 2026
I'd like to report a specific bug when attempting to highlight and select text on an epub on the iOS app.

Zotero app:
Version 2.0.5 Build 433

Devices tested on:
iPhone 13 mini iOS 18.7.7
iPhone Xs Max iOS 18.7.7
iPad Air 5th gen iPadOS 26.3.1(a)

All these devices have the same version and build of the Zotero app. The iPad does NOT have this bug, while both iPhones DO have this bug. As far as I have tested, this is specific to .epub file formats.

The bug is that when a paragraph runs onto two pages, the text on the second page becomes unable to highlight or select. New paragraphs are selectable, and the "run-on" text can be selected in addition to prior paragraphs, but if the selectors are pulled up into the "run-on" paragraph, then it disappears entirely and all text becomes unselected. "Run-on" paragraphs cannot be selected at all.
