Hi Tarun Singh Rawat,
I have installed the latest version 6.11.6 (1833) and related to my bug no. 2 mentioned above, it feels a little bit more fluent. But just a few minutes ago, I had a similar bug: I have copied one item to another vault on my smartphone. Same time, Enpass on my computer was locked by itself (due to time limit). Unlocking took a little longer than usually and after it was unlocked, it stumbled like hell including the title bar saying "App is not reacting anymore". But after a few seconds, it recovered itself.
Regarding bug no. 1, I will keep an eye on it and will let you know, if it has improved.
Thank you and kind regards,
Alex
