Hi, @sosnovsky Do you know any workaround for this one?

Hi @martgil, this bug is quite difficult to reproduce - it happened for me a couple times and now even larger PGP/MIME messages are decrypted without errors (the same for customer who initially reported issue).
Affected user can try to restart browser or try to open this message in another browser (firefox)

Thanks, Roma. I will also try to find a way to reproduce this in a manner that increases the likelihood of replication, if possible.

Ok, initially I was able to reproduce by sending reply with 4mb attachment to password-protected message from FES, but now the same message is decrypted without any issues.
