What are the limitations of the Collabora server

Hello @Tex. Thank you for your support.

Currently, I have installed a Collabora server on a VPS with Ubuntu 22.04 and connected it to two instances of Nextcloud, totaling 20 users. With this test, I aim to assess how many users can effectively collaborate on a single document simultaneously and identify any limitations in usage. If successful, I plan to connect additional Nextcloud instances to the Collabora server in the future.

What are the limitations of a trial or home version, and what differences does it have compared to a professional subscription? This includes considerations for updates and support requests, following the SLA policies.
