Issue in file extension in honor p20 lite

[arvndtodi]

When I attach any image or file in gmail directly from file manager or whatsapp, file name gets renamed randomly in gmail like 24631 immediately after attachment.
Also file extension gets deleted. So when recipient of that email downloads the attachment, file gets downloaded like "24631" without any extension.

Whats the issue ?

Does it relate to file manager. I am using file manager provided by huawei by default in phone.

It's your file manager.
Use a different one from the play store.
And you should be sending these directly from your apps
