Ungoogled Chromium --no-sandbox warning

I’ve installed ungoogled chromium using the instructions from the link below, but now I’m get a message upon starting it complaining about how ‘–no-sandbox’ is an unsupported argument from command line. I haven’t encountered this when installing previously, and would much rather it didn’t appear. Any help welcome and appreciated.
