Deeplink opens correct send flow screen on iOS:

Bitrise build https://app.bitrise.io/build/2a9d2382-e406-41b7-82dc-22de573091fb?tab=artifacts

Nice!

The related test file only has a single snapshot test. Since we plan to update this confirmation to a redesign confirmation, I think it's fine not including a test now

[sleepytanya]

Bitrise build (Android release) https://app.bitrise.io/build/5fad22ac-97be-4459-b9ea-21eb51b2580b?tab=artifacts

Fix doesn't work on Android, clicking on the link opens MM app but doesn't start the Send flow:

android.mp4

Bitrise build (Android release)

• Fix doesn't work when clicking on the deeplink: nothing happens; the send flow does not start

• Fix works when scanning the QR code

fix.not.working-.click.on.deeplink.mov

fix.working.-.scan.QR.mov

[OGPoyraz]

@Unik0rnMaggie thanks for taking a look at this.
Because of the quality of the video I cannot confirm but can we make sure the link from the first fix.not.working-.click.on.deeplink.mov is actually equal with the link (on top of alert) in the fix.working.-.scan.QR.mov?

There should be no discrepancy between iOS and Android because fix is purely setting a forgotten argument in JS context.

Also this was the PR that we introduce that bug: #12321
(just putting here in case if anyone wants to compare before and after)

[Unik0rnMaggie]

Hi @OGPoyraz sure, glad to help! And apologies for the poor resolution.

Here is another video: I'm using the same payment link for both actions:

• clicking on the deeplink: not working
• scanning QR code - working

Same.payment.link.mov

Please let me know if you need anything else!

Thank you!

[OGPoyraz]

Thanks a lot @Unik0rnMaggie, it seems like both are the same links, weird.
I am currently trying to make a local Android build work, if I manage to test it on my end, will update here.

By the way just an info for you, if we are purely testing deeplinks, we should scan that QR code with your camera app, not the QR scanner in the MM app, because they are not the same flow.

[Unik0rnMaggie]

Hi @OGPoyraz thank you very much! And duly noted! I will keep this in mind for future testing!

I tested again using the device camera to scan the QR code and it's the same behavior as when clicking on the deep link:

Nothing happens and the send flow is not starting

fix.not.working.mov

Marking this PR as No QA needed to merge it as we discussed in the release thread.
