Hi,
I did the following:
===========================================================
user@pc:~$ snap info libreoffice

snap info libreoffice
name:      libreoffice

  LibreOffice is a powerful office suite – its clean interface and
  feature-rich tools help you unleash your creativity and enhance your
  productivity. LibreOffice includes several applications that make it the most
  powerful Free and Open Source office suite on the market: Writer (word
  processing), Calc (spreadsheets), Impress (presentations), Draw (vector
  graphics and flowcharts), Base (databases), and Math (formula editing).
commands:
  - libreoffice.calc
  - libreoffice.draw
  - libreoffice.impress
  - libreoffice
  - libreoffice.math
  - libreoffice.writer
  - libreoffice.base
channels:                 
  stable:    5.3.0.3 (17) 374MB -
  candidate: 5.3.0.3 (17) 374MB -
  beta:      5.3.0.3 (17) 374MB -
  edge:      5.3.0.3 (17) 374MB -
===========================================================

In channels you notice currently there is 5.3.0.3 available in all of the channels including "stable".

Now look at the instruction how to install LibreOffice using Snap at: https://www.libreoffice.org/download/snap/
and there is command:
sudo snap install --channel=beta libreoffice

Above command is perfectly fine, but there is no need for channel "beta" if the same version is available in "stable". In my humble opinion users should be encourage to install as stable software as possible. In this case there is no need to point user to beta channel in future they may get unstable version when they refresh snap.

I suggest to change command from:
sudo snap install --channel=beta libreoffice

to:
sudo snap install libreoffice

and end-users will currently get the same effect.
