work offline! it seems like the definite solution to the paralysing instability in the program. I can barely read one abstract before I have to reload while on my Mac og even worse download again while on my phone. This basically makes working with Rayyan impossible and renders it a useless program. otherwise quite useful.
Sorry for the inconvenience you encountered in using Rayyan. The issues you mentioned have been solved by now.
Note that you can use Rayyan offline on your mobile device (iOS and Android).
