S/MIME save decryption password in DeskApp

[A Former User]

I installed S/MIME plugin and it works as expected. When I want to sign a mail, I click on the “Sign” icon, DeskApp asks for the decryption password and signs the mail.
Unfortunately DeskApp do not store the password, so I have to enter the decryption password for every mail. I enabled this parameter:

DEFINE('PLUGIN_SMIME_PASSPHRASE_REMEMBER_BROWSER', true);

Kopano 8.6.5.0
WebApp 3.4.17
SLES 12 with all patches.
DeskApp 1.9.7

Any ideas how to store the decryption password in DeskApp?

To answer my own question,
restarting Windows, now DeskApp remembers the decryption password.

Strange. Same here but password will not saved in Deskapp. Using here UCS 4.4 (Kopano 8.7.1.0). Clients are Windows10 and KDE Neon Linux. On both the same. The password on the Deskapp will not be saved for the session. For every mail we must enter the decryption password.
