Describe the bug

For my case, I upgrade drop-in SDK from 6.5.0 to 6.11.0, and i found that previously BraintreeClient will convert default params to lowercase, and now it removed. In my application the applicationId contains capital letter, I think the scheme is not accepting capital case, since it prompt AppLinkUrlError if I put capital for android:scheme.

I found the BrainTreeClient constructor able to pass the custom url scheme, but on top DropInClient not able to modify the setting of BrainTreeClient

To reproduce

• Open drop-in UI
• Add paypal as payment method
• Login paypal acc
• Failed return to app

Expected behavior

Should able back to app

Hi @Chaos2805 thanks for using the Braintree SDK. For context, we stopped lowercasing the applicationId used for creating a custom URL scheme because capital letters are still valid URL characters according to RFC 2396.

Can you provide a snippet of your AndroidManifest.xml?

Original code before upgrade to 6.11.0

After upgrade to 6.11.0, it able redirect back to app after adding paypal but always return UserCanceled error.

And the main root cause i found is deeplink url = "com.project.whitecoat.braintree://onetouch/v1/success?token=EC-6FR52205SB437450R&ba_token=BA-1P1504025R832413F" and matchDeepLinkUrlScheme function using package name which is "com.project.WhiteCoat.braintree"

I wonder where to change the deeplink url return.

[Chaos2805]

The success-url paased into browserSwitchRequest was with capped

but returned deeplink url was in small capital letter
