Would not send mail from other than Mail apps

Question

I often want to share links in Safari via Mail. I usually share (button next to the address bar) and click on Mail and send it to the person of my choice.

But, since I updated to iPadOS 16 (December 2022), it doesn't work anymore from out-of-Mail. I mean that when I try to send mail from any other app than Mail by sharing, it does show the send options (as if drafting a normal email), everything seems to work fine, I compose, I send. But the email never gets sent! I checked in my "Sent" mailbox, where the emails I've sent normally go to, but the one I've tried sending isn't there, even an hour after.

When I send the same email (same email/person/sender/subject...) from Mail app, it works just fine, I just have to wait for about 10-20 seconds to get the email to be loaded in the "Sent" mailbox.

How to make me able to send email from any app again?

Note : I am on iPad 6th generation running iPadOS 16.2

Disable Undo Send Delay

This is a weird behavior for Mail on iPad. The only way I've found to avoid having this problem is to diable Undo Send Delay, a new feature that came with iPadOS 16 that made you able to retract a sent email (so obviously not sent yet) to avoid accidental sending, in Settings :

1. Open Settings app
2. Navigate to "Mail"
3. At the bottom of the menu, under "Signature", click on "Undo Send Delay".
4. Click on "Off"

For an unknown reason, the Undo Send Delay makes sending from other apps impossible. It is normal you have to wait 10-20 seconds because the Undo Send Delay was parametered by default to be 10s.

This works for me, I can now send anything I want from another app by clicking on Share.

Good luck!
