An updated version of the LibreOffice snap was published earlier today in the snap store (beta channel).
If you are using the snap already, or if you feel like testing it, now is the time to upgrade to that version (184.108.40.206) and let us know if you find issues with it:
snap install --beta libreoffice
Note that it can coexist with the official ubuntu packages. If you want to remove those packages and use exclusively the snap, do the following:
sudo apt remove "libreoffice*"
sudo apt autoremove
This new release addresses a handful of bugs.
And if you need to report a bug against the snap package (current stable version or update in the beta channel), please use the tag "snap" and paste the output of the following commands:
snap info --verbose libreoffice core
Note that the snap is currently available for amd64 and armhf architectures only. There is a known build failure for i386 which is being actively investigated.
