No nextcloud client icon in Linux Mint tray

After update from linux mint 18.1 to linux mint 18.2 i do not see icon for nextcloud-client in system tray. Instead the icon i see empty place.
nextcloud error
Before update it’s work fine.

I already read a similar topic: no nextcloud icon in panel on Mint and set 60 seconds delay after start up. But this solution is not work for me. :frowning:

Nextcloud client version: 2.3.2-20170823.130651~xenial1
OS Version:
Kernel: 4.8.0-53-generic x86_64 (64 bit)
Desktop: Cinnamon 3.4.6 Distro: Linux Mint 18.2 Sonya

Same for me. Delay workaround doesn’t work.

System
Linux Mint 19.3 Tricia 64-bit
Kernel Linux 5.0.0-37-generic x86_64
MATE 1.22.2

No tray icons. Any suggestions?

Asume:
Found they’re hiding under /usr/share/icons/hicolor/x/apps/Nextcloud_x.x
(e.g. /hicolor/128x128/apps/Nextcloud_error.png)
maybe the have to be copied to the “right” location

Or renaming to “Owncloud” ?:
Like mentioned here: https://github.com/nextcloud/client_theming/issues/169

Changed my mate theme these days… voila nextcloud-sync-client icon appears
So it seems to be a Linux Mint Mate “Apperance Preferences” topic.
