App is great, please update more

Hi, i updated my review to this latest version. There are few problems I faced after updating:
1. Sometimes messages sync slow and not up-to-date. I have chatted on fb web for a while but there is nothing new in astro app. Therefore I have to keep on opening fb web to continue chatting.
2. Seen status: so wrong, mainly wrong all the time.

Please update more.
Hope it helps
