<!-- This is a bug report tracker. For feature requests and support, please go to the forum: https://support.delta.chat Please fill out as much of this form as you can (leaving out stuff that is not applicable is ok). --> - Operating System (IOS): - Delta Chat Version:2.49.2 -Expected behavior After expanding a collapsed long message, the text should remain readable with a normal font size, and users should be able to easily select and copy the full message content. -Actual behavior When opening collapsed long messages, the displayed text becomes too small and difficult to read. Additionally, selecting the full message content is inconvenient or sometimes not possible. -Why this is a problem This negatively affects readability and usability, especially for long technical messages, logs, or large text blocks. -Suggested improvement * Keep a normal readable font size after expanding long messages * Improve full text selection and copy behavior for expanded messages
