Single message sending to external and internal recipients sometimes fails #5916
Description
Customer reported an issue which occasionally happens for some users - they are unable to send emails when both internal and external recipients are included (so sending should include encrypted and password-protected message). In this case error Google returned an error when sending message. Please help us improve FlowCrypt by reporting the error to us is shown.
This issue is fixed when user sends the same email separately to internal and external recipients, or by reinstalling the extension.
Need to find a way how to reproduce this issue and find the reason for sending failure.
