If loading doesn't progress past 0%, it's usually simply because Labster needs to be loaded in a new window, and not within an iframe. This is for security reasons.
To fix this, please make sure you set up the LMS system so that all Labster links open up in a new window.
This varies a bit from LMS to LMS, and if you are unsure how, please ask your LMS administrator how to do this.
If Labster is opened within a small iframe like the above, it may cause the loading to not be able to start for security reasons. Please set up the links to open Labster in a new window.
Please do not hesitate to reach out to our Support Team if you have any questions or are in need of assistance.
