Open an entry of text with several paragraphs that fill the screen, enough that scrolling is required. Triple-tap to select a paragraph. Tap and hold the rightmost selection handle and drag down to select from the current position to the end of the entry.
Text does not scroll into view. It's nearly impossible to select more text. This happens with the standard Apple keyboard and the G-board addin keyboard.
Compare how selection and scrolling work here on the forum with the behavior in Diarium. Diarium selection ought to behave like this forum. This bug makes for a very frustrating experience because I need to frequently update my template using text that I copy from the end of an entry.
