Submit login form sometimes don't login the customer

[ImoralesMV]

Hi, I’m developing an app embed block for my theme app extension. This app embed block reads query parameters in the URL and if there is a specific parameter in the URL, I put some customer credentials in the form and then submit the form to login as a customer. When I do this, the store shows me that I’m already logged in, but sometimes even though it shows me that I’m logged in when I go to the customer profile or when I reload the page it turns out that I’m not actually logged in. I’ve already tried instead of using the form submit to click the form button with javascript and I get the same problem. This doesn’t happen to me all the time but it’s quite common. Any ideas?
