Major Flaw - PDFs are not readable in the APP

Mendeley desktop is super useful, mendeley mobile app is virtually useless. I use mendeley to not only save my sources and citations, but also to view my PDFs and write notes on the PDFs for future reference, but all that functionality with the PDFs is not present in the app.

The PDFs I download into my computer are not available in the app. I see the source, but I’m unable to read the content of it, making this ipad close to useless.

The only solution I have found to be able to open my PDFs, is to do this first on a computer: Open the PDF in Chrome, select the print option, save it as a PDF somewhere else on you computer(this sort of gets rid off the original PDFs metadata related to authors, sources, etc.), and then import that other PDF into the Mendeley App. Since some important metadata will be missing, you will have to manually correct the title, add the authors, publication, date. But at least this way, when you sync your account, you will be able to find your PDFs on the ipad.

Still committed, but frustrated.

I like Mendeley. Haven’t found a PDF organizer that meets my academic needs better yet... but right now I can’t use it on my iOS devices... which is where I live and do most of my work. It just crashes on launch. I’m left sending it to my laptop and then reading / reviewing though another app on my iPad. I reached out to support... and they said an update is coming... and I know app review takes a bit... but so frustrating (some is my fault and I’ve been living on the betas for a while... and had no expectation that it be fixed for because I was on the beta, but it is released now). If I could encourage the developer... I hope that you could take a your iOS version and make it the best, because to me it’s the best place to read and review my journal articles. I’m assuming shortly there will be an update to fix the crash on launch... but what I want is for them to also take on new cool features of iOS (dark mode, Siri shortcut support, editing in other apps... etc). I’ll be ok if just opens, but I want you to be taking it further as this is my platform of choice.

Lots of potential, but recently too buggy to use

I’ve used this app for the last year, and it had been a great way to read academic papers while on the go, allowing me to highlight text, leave comments, and then sync it back to the desktop app. It always seemed a bit slow, but functional, until about a month ago. Since then, it has really struggled to refresh, sync, and download PDFs. It has crashed multiple times recently, just trying to scroll through a PDF.

This app can be extremely useful, but it really needs to be updated. I love the ability to easily access my mendeley library and keep everything synced, but the app’s recent issues have made it almost useless.

Please fix all these bugs! I’m looking for other options but haven’t yet found anything as seamless to sync between mobile and desktop. I’m keeping my fingers crossed that things improve soon!
