Good app 1st use only!

Seemed like an amazing app the first time I used it. Since then, every subsequent attempt to open the app results in the spiny wheel of death at the loading page.
Also, there is no bookmark function on the phone app - a bit useless when you can’t save your favorites.

With work, this will be an excellent app!

Still unable to load app

After initially seeming to work on first run-through, I'm now met with the same orange screen with loading wheel as other reviewers. It is not 'fixed on recent version'. Is this a download screen? - in which case you need a progress bar. Please address this as lack of mobile compatibility on my device means I will not be rating this app more than 1 star. As an institutional purchase from Elsevier of multiple thousands I expect better.

Perpetual loading

This was a 4* app after the openathens login saving details problems were fixed.

I login using openathens but for past month or so it gets stuck loading when the app is launched after initial login.

I’ve tried reinstalling several times but to no avail...still the same.

Can’t keep reinstalling every time I need to use so will have to ditch it until fixed.

Also feature wise, it would be great to have a “bookmarks” section where links to whole books and journals could be saved not just individual chapters or articles.

I would love to be able to just click on Lancet ID or Mandell’s principles of ID and go to index easily rather than searching every single time.

If above were enacted it would go straight to 5*
