I can't log in to Target app using iphone SE 2020

I'm not using a VPN to connect to the internet. I'm confused as to why I would need to clear the cache of the safari browser since I'm using trying to login on the target app, I'm not using the safari browser. Either way I did try that and it didn't change the error message I get with in the app.

This is what I see when I try using the app, from when I open it till I get the error message.

Thanks for clearing up the Safari connection. Yes, I enter in my username and password and then that error happens.

When I switched to this phone, I could not sign into the app. It would say my account did not exist. Then I tried to log in on my pc, to find that my account had been locked. It took three calls to target customer service to unlock my account on my pc but the app kept saying my account did not exist. Customer service told me that Target was undergoing an update to their system and that this was causing a disruption for some customers. After the last reset of password, target customer service had my log in to the app and that is when the invalid parameter error started.

They say they have never heard of this happening but I found a reddit, from a year ago, referring to the same problem but with an android phone. I couldn't find anywhere in the discussion that a solution was found.

Can you suggest what my settings should be on Safari to get this to work.

I just got this phone and when I did the side by side transfer between iPhones, I thought that included all the settings. The app worked fine on my previous phone.

The target tech team sent me directions of how to solve the problem but for android phone. So I couldn't do any of what was suggested to fix the problem. But one of the suggestions is to "force stop" the app.

I tried to log in and got that invalid parameter screen and instead of hitting cancel, I did a reset (not sure if I'm using the right terminology). For my SE 2020, I press the volume buttons up and down then the side button until the screen goes black. Let everything load again and tried logging in and it worked. I don't know if this is the solution but it worked for me on the second try. Give it a try and maybe it will work for you too.
