Bug?

Do you have any third-party plugins installed? If so, which ones?

No

Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

It looks like mostly an iCloud issue, but my G Suite trash folder is also struggling to sync.

Is the issue reproducible with a particular attachment, message, signature, etc?

Not that I’m aware of.

Description

Basically a few folders from my iCloud email are not syncing at all (along with the trash folder from my G Suite). Running Mail with Debug Flags shows only one error, and the popup saying “Encountered an error while syncing” is permanently in place. The error reads:

/Applications/Nylas Mail.app/Contents/Resources/app.asar/node_modules/fbjs/lib/warning.js:36 Warning: Each child in an array or iterator should have a unique "key" prop. Check the render method of SyncActivity. See https://fb.me/react-warning-keys for more information.

There’s no correlation between the folders that would indicate it’s an account issue, so I can’t work out why this isn’t working. I also have 2FA enabled, using an app password if that helps at all.

this should be fixed on 1.0.26 which was released today! Thanks for your patience!
