Here are some suggestions on resolving the issue with attachments not showing up in emails:

1. Check your email client settings: Make sure that attachments are enabled in your email client. If your email client is set to automatically delete attachments, try setting it to not delete attachments.
2. Check the size of the attachment: Many email clients limit the size of attachments. If the size of the attachment exceeds this limit, the attachment may not show up.
3. Check your internet connection: A poor or slow internet connection can prevent the attachment from loading.
4. Check the file type: Some email clients do not support certain types of files. You may need to convert the file into a different format to get it to work.
