re: "My Android version is only 5.1. Is there any chance the app could be compatible to older versions in the near future?"
They only recently delivered something that works on Android.
It is unlikely that the Android team has plans to make the app backward compatible with older versions.
WIth the old app I would sometimes receive notifications of messages or interview requests, and sometimes I wouldn't. When I saw there was a new app, I thought great! There is only one thing that I expected to be better without a doubt - notifications. Alas, I do not receive any notifications. So I manually have to check multiple times per day. For an app that relies on communication with each other, you would think that alerts would be a part of the app. And not just the choice to turn on all alerts or none, rather the choice to turn on one for messages, one for proposal requests, one for interview requests.
EDITED: I initially wrote about lack of mobile resolution support in the browser, but it seems to have been implemented recently.
For those of you on 5.x Android, use the website instead. It offers mobile resolution now instead of "desktop mode" resolution
Excellent work! Thank you!
I received the request to upgrade on my existing app, and installed the new version. A few minutes after logging in I received an email An unknown device or browser has been used to access your account, The location specified in the email was unknown to me and I went through the password reset + uninstall new app process.
It was a scary experience...
