Templates stuck in outbox#605

I prepare templates that are long and includes some attachments but they always stuck in the outbox when I use them. It makes templates features useless.

I deleted and installed the app several times but the issue remains. I hope there is a quick fix because I need this feature a lot.

I am on Big Sur 11.3 and using app store version of the app.

I am having the same issue. Did you receive any solutions? This is quite frustrating because I rely on templates to make everything happen. I too have a template with an attachment.

Big Sur and iOS apps are being used here.
