I am making a DAPP using React Vite, and i want to switch from using window.ethereum to MMSDK.
So, what happens is that even if I have the extension it opens the popup when the Submit Button is clicked.
Here are the screenshots for this:
My Extenstion:
If I click Submit:
There are no errors but the popup comes even though I have the extension.
Actually I cant give links and more images so please check my StackOverflow post: https://stackoverflow.com/q/76563765/18320612

Thanks for your reply! 
@nakedwinnie I recently noticed a warning is coming when the button is pressed:
Hello @thecodingsage !
Welcome to MetaMask community !
I deployed your application and tested it on an old version of Brave (Quite old and not updated for a long time), there was an error related to the fact that provider MetaMask is undefined:
BUT! When I tested this in my stable and updated version of Chrome, here is a successful connection to the MetaMask wallet via the SDK and displaying the connectable address (there are other errors below 
):
What browsers and operating systems have you tested your application on?
You should probably also update @metamask/sdk to the current release version “0.3.3”
Hey @snwlprd.eth
I have Brave Browser version 1.33.106 and can’t update it as I have an old MacBook Pro 2009 Mid with MacOSX 10.11.6.
Also, the latest version of the @metamask/sdk says no error, and the Install MetaMask Extenstion button works!
Unfortunately, the primary function doesn’t work and the popup still comes, but it says connected on the extension:
Also, is there no way but to buy a new laptop for this to work? Is there any hope?
BTW, I have version 10.32.0 of the extension.
Thanks for your reply!
Also, I want add that it might not be a problem with the browser or the operating system as the test-dapp from the MetaMask docs works.
Here is the link to it if it helps: https://c0f4f41c-2f55-4863-921b-sdk-docs.github.io/test-dapp/
Looking at the source code of this example, you can see that the ethers and @metamask/onboarding libraries are used.
You may also use the @metamask/detect-provider library, which is more likely to work in your environment.
Can you please provide the source code? It’ll sure help! (Sorry for the late reply)
Add this to the URL of the Github:
/MetaMask/test-dapp
@snwlprd.eth @nakedwinnie Thanks so much for all your help!
Now it works on both Desktop and Mobile!
But I have a small question even if I use @metamask/sdk, do I have to use the MetaMask Mobile Browser?
Once again, Thanks so much for all your help!
@metamask/sdk generic lib but probably your Brave current version is too old but you can play with options object config which is an argument maybe it will give some result
