Problem log in on iPhone

I have paid 12 month premium and using LingQ daily on my PC. I tried to log on my iPhone. I have installed the app, but not used it for long time (months). But I don’t see any log in option. Instead the app want me to add an card info for premium account.

How do I log in on my iPhone without paying? Do I have to enter card info despite I have already paid for a 12 months membership?

@MarkSiip Are you sure you are logging into correct account? Your account is Premium and you should be able to login and use it on whatever device you want.

I can now log in to my account on my iPhone!

Before a log in window was not shown.

@MarkSiip Great, thanks for the update.
