What issue do you have?

Having an issue others have seemed to have in the past - OneDrive fails to sync with the following error:

Last error: Error: Could not retrieve account details (drive ID, Account type. Error code: SELF_SIGNED_CERT_IN_CHAIN, Error message: request to https://graph.microsoft.com/v1.0/me/drive failed, reason: self signed certificate in certificate chain

My MacBook is pre-configured to use a self-signed subCA, which all browsers and the like are pre-loaded with when the OS is installed, so this is expected.

Seeing past recommendations to specify custom TLS cert(s), like this one.

However, the native MacOS Joplin App doesn't currently seem to allow this configuration for OneDrive sync.

Am I missing something? Not seeing anything in the FAQ or docs that seems to address this.
