Please fix for iOS 13 – Mendeley (PDF Reader) Review

I use Mendeley in every capacity of my academic workflow (Chrome importer, LaTeX .bib exports, Overleaf integration, annotation, and reading). Though I understand that not many people were happy with the layout or stability of the iOS apps, at least they worked in iOS 12. Now, the app will not even start without crashing (starting the app loads the logo then closes abruptly). I beg the developers to please update the apps to at least functional levels for iOS 13, iPhone and iPad. iOS 13 was not a surprise to any other app developer, as Apple provided the resources to update apps long before the public OS launch. Elsevier, please give your developers the money and time to develop functional apps if you plan on advertising them for these platforms. If you are discontinuing the apps, then just do so and update your marketing. It is simply unprofessional and frankly embarrassing of an ordinarily esteemed and prestigious organization.
