I am using Joplin 2.3.5 (prod, darwin) on a work computer which was just upgraded to Big Sur (11.5.2 (20G95) ) with a new firewall system. I am syncing to Dropbox. Syncs are now failing with the error "unable to get local issuer certificate." I downloaded the certificate from my employer and added it to Keychain Access but I still get the error.
Several earlier answers involved going to Preferences -> Synchronisation -> Advanced and turning on "Ignore TLS Errors" but I don't see that option.
This is a work notebook so I don't care that the content is exposed to my employer, but I do want to be able to see it on other systems. How can I get Joplin to either ignore the error or use the certificate my employer provided?
