                            HorizontalOptions="Start"/>
                   </Grid>

Note that if password is entered before userid then taps to change focus work, even if password entry is completely deleted, userid entered, and password re-entered.

I have created a sample:

@hartez I cannot reproduce the issue. I think you were the one who fixed #12246, could you test the attached sample?

[NeilN1]

Hi @jsuarezruiz Your sample does not include Material which seems to play a part in this issue.

[PureWeen]

@NeilN1 can you try with this repro that uses material and 5.0 pre5?

I'm not getting any crashes

Since we haven't heard from you in more than 30 days, we hope this issue is no longer affecting you. If it is, please reopen this issue and provide the requested information so that we can look into it further. Thank you!

@Redth I have exactly the same issue, and no workaround seems to work.

I tried @PureWeen 's sample and it works, so, after researching, I found out that this issue is being triggered with iOS password generator, so, in order to replicate it, you have to implement a "working" Sign Up page either using Associated Domains plus Keychain, or using an authentication provider (Like Firebase)

Please, try this sample (Remember to fill Entitlements.plist with a valid domain and set up that page with a valid JSON)
: Issue12868.zip

Please, be aware: iOS MUST prompt you to use a strong generated password, you HAVE to select "Use own password", otherwise the app will not freeze at all. If iOS doesn't prompt you anything (i.e. you didn't set an associated domain), the app will also not freeze.

I tested this sample using the latest Visual Studio for Mac, and with an iPhone 8 (iOS 15.0.1)
