Subscription mails are not previewing charts

I am using V0.50.8

I have a dashboard with multiple line graphs and a table, only table is being previewed and all other line charts are not. line charts are just showing up as name even when i mail a single chart.

In addition is there any way to export all the charts into excel (only underlying data is in excel as of now)?

Hey there, do you mind sharing a screenshot about your first question?

About the second one, there is no way using the UI, but you might do it using Metabase API.
