Mostly better, room for improvement
The negative reviews here make valid points, but for me the new format is a significant improvement over the bloated, inaccessible previous format.
Each issue takes a fraction of the storage required before, the text can be copied and pasted, resizable text is a blessing, and landscape support. As pretty as the DPS stuff was, it was not always very functional.
Accessibility can be further improved with Speak Screen support (have not tried VoiceOver but that should be there as well), Split View and Slide Over for iPads, and keyboard shortcuts for navigation. Maybe some choice of typeface (Dyslexia font maybe?).
The multimedia and embed of web site and sliding panels are gone (at least for now) but they were a little annoying and distracting to me.
Its bad that older issues are no longer available in the app. Hopefully it is in the plan to convert those to the new format and restore access to that material over time.
A stretch goal would be to include some sort of index to the available issues so you could search, download (if necessary) and open to the reference. Far more do-able with the new format.
