Phantom iOS browser sending GET instead of POST from submit buttons

[KeithWalton]

Summary

Starting at about the same time as the most recent Phantom iOS app update (4 days ago), my users have been reporting blank screens in my app when they click on buttons. By testing it and comparing to other browsers, I found that buttons of type submit are all sending GET requests instead of the expected POST when using the Phantom browser. You can see it in action here:

https://pritv.io/explorer?collectionId=1

Click on PriTV Toolkit. It will work in any browser except for Phantom (I've only tried IOS, not Android). The response code is 405 since the page doesn't support GET on that method.

Example

https://pritv.io/explorer?collectionId=1

Steps to Reproduce

Click on PriTV Toolkit.

I'm using a .NET Core 7 web app.

This is what the button renders as:
PriTV Toolkit

I also created a new project with just the starter page with a button. The same thing happens.

Phantom Version

23.13.0

Is there an existing discussion for this?

Hey @KeithWalton,

Thank you for writing in!

We're looking into this issue. I will follow up as soon as I have more info.

Thanks. I found another way to reproduce it: https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_form_method_post

If you enter data and click submit, the data won't show on the resulting page (compare to other browsers which show the data).

It will likely be around 2-3 weeks.

I see that 23.15.0 has been released, but the problem is still there. You can reproduce it here: http://solandia.io/postme

Thank you for this example app! We will investigate.

I noticed the pritv site appears to be rendering as expected now. Did you make updates to handle the post conversion issue?

[KeithWalton]

Any update on this? GETs really don't work well for us- when a user click the back button they get that annoying "are you sure you want to post again?" We can't bring on any new clients until this is resolved.

Hey @KeithWalton, I am sorry for the wait. We are investigating but I don't have any meaningful updates yet.

[KeithWalton]

Yes, we switched some of the posts on our site to gets, but there are still some things broken.
