4.1.8.0 app version stuck in logo

Hi,
I have been using Airdroid for a very long time and everything was working fine (I love the app). But with the last version, 4.1.8.0 I am having problems. It was working fine for a while, but one time it got stuck in the Airdroid logo while opening the app ant it gets stuck there. I tried clearing data and cache from the app. I have updated my cellphone from a 6.0.1 Rom to a 7.1.2 one. For a while was working fine but the problem has occurred again. In the end I have downgraded to a previous version 4.1.7.0 which works fine. Any suggestions about how to solve this problem with last version?
Thanks

Just by chance I have left the 4.1.8.0 App opening with the logo in the screen and after more than 2 minutes it opens (so it was not stuck).
Weird, it was working fine for a while
