AirDroid3 Windows stating phone software is out of date

I just update my Air Droid on my Nexus 5, running Lollipop, to version 3.0, see screenshot, and when I try to log in using the new Windows Desktop Client it tells me that the phone app is out of date. I am able to connect via the web, but am wondering if anyone else is have the same issues with the new software?

I am also having this same problem on my Galaxy Note 4. I'm able to use the web version but I can't use the installed client.

Aikijujutsuka, Some how uninstalling and reinstalling did the job. Thanks so much for that suggestion.

For me the app on the device also complained that it was out of date, and gave me a button to tap that took me to the Play store. Tapped "update" button there, updated, all good.

Same thing. Moto Mini running 4.4.4. Device app says it's up-to-date; Window app says it's not. Uninstalled and reinstalled apk. No change. Can connect via web.
