Gmail won't send emails with attachments

[JG322779]

My Gmail app refuses to send emails with attachments. Is there any way of getting help from Google?

This is a Sony Mobile global user based forum, you should contact Google directly.

Do you have stamina mode on? how fast is your internet connection?

How can I contact the Google directly?

WiFi speed is good, stamina is off.

All my email accounts that I use on my phone stopped sending attachments, not just Gmail actually.

Boot in >>> safe mode and test it

How large are the attachments? 

Gmail > swipe left to right > outbox > what do you see?
