I have a 52-page document authored in Pages that contains many equations, most of them pertaining to matrix algebra with many subscripts. Using Pages v13.2 on macOS 14.0 Sonoma (23A344), the exported PDF version of the document does not render the equations correctly. In particular, equations containing a vertical bar "|" are rendered without the vertical bar in the PDF document. For example, an equation for a probability expression of "P(x|y)" gets exported to PDF as "P(x y)". In particular, the Pages "blahtex" form for a discrete-time system equation is \mathbf{x}_{k+1} = \mathbf{\Phi}_{k+1|k} \mathbf{x}_k + \mathbf{u}_k + \mathbf{\Gamma}_{k+1|k} \mathbf{w}_k In Pages, this gets correctly rendered as whereas, in the exported PDF document, it gets incorrectly rendered as Also, using \vert or \mid to generate the "|" in the equation does not help; the PDF export is still missing the "|" symbol. If I save the document in Microsoft Word format and then export to PDF, the equations are rendered correctly. Reverting to Pages v13.1 from Time Machine does not fix the issue; the exported PDF is still wrong. It should be noted that when I used Pages v13.1 in Ventura, exported PDF equations rendered correctly. There may be other formulations that are broken that I have not yet encountered. In addition, my equations in Keynote suffer from the same problem when I export them to PDF. I know that macOS Sonoma removed EPS support, but it looks like other things got broken with this change. I don't want to convert all of my Pages documents to Microsoft Word, but unless this gets fixed, Pages has become useless to me for technical documentation. I'm an engineer with a lot of documents, so this has pretty much brought my workflow to a halt. I've submitted a bug report to Apple (FB13208972), but I am interested if anyone else is experiencing this problem.

Am I the only one having this problem? The Music app on iOS 17 beta does not cleanly seque between songs that are intended to have no gap between them. When gapless songs are played (e.g., Pink Floyd's "Dark Side of the Moon", The Beatles' "Abbey Road"), a noticeable gap is heard between songs. These are songs in my music library that I sync from my computer, not Apple Music streams. It should be noted that this bug also exists in iOS 16.6, and I've verified that the problem does not occur on a older phone running iOS 15.7.8. More importantly, when I put the device in Airplane mode, the songs seque correctly, without any gaps. I suspect that the Music app is phoning home to Apple (a bad practice in and of itself) and something is interrupting playback queuing. Even when I have Cellular access turned off for the Music app, and am not connected to Wi-Fi, the problem persists. The only way to make gapless playback work is to turn off all of the device radios via Airplane mode. Understand that this is NOT a cross-fade issue. It is a gapless issue. And it's not an Apple Music streaming issue. The problem seems to be more prevalent for songs encoded as 128 kbps AAC. In comparison, the Music app on macOS (Ventura, 13.5) operates correctly. It's only iOS that no longer performs gapless playback. I've filed bug reports (FB12992049 and FB13019931), but have not heard anything from Apple. Like I asked at the beginning, am I the only one having this problem? It's extremely maddening that Apple can't get this right. I can't play my Pink Floyd, Alan Parsons, and my other AOR playlists, including my late 60's Beatles. Steve Jobs would be rolling in his grave.
