geolocation website wordpress changes

This websites is a geolocation service (made with wordpress) that lets a visitor locate a phone by entering its number; the country prefix is shown automatically according to the visitor’s location. The service costs $0.89, after which a subscription of $49.80 starts the very next day.

Please fix exactly the following points:

-Desktop flag bug: When I open the site in DESKTOP mode (e.g., from Italy) an Indonesian flag flashes for one second (my server is in Indonesia, maybe that’s why). This must be fixed. The input bar at the bottom of the site shows the same issue and must be fixed in the same way.

-Wrong-number flash: After I enter a phone number and click Locate, a number I never typed flashes for a second. Fix this.

-Email field overlap: On the next page, the email-input bar shows overlapping text (see screenshot). Fix this.

-Checkout issue: On the final checkout page, Stripe payment works on desktop but not on mobile.

-Cross-device consistency: Make sure that on every device mode (phone, desktop, etc.) the site works in the same way, without bugs.

-Subscription flow: Verify that the subscription works correctly (I’m using PMPro).

Deadline: 1–2 working days
Budget: Very low – an experienced WordPress developer should find the task easy.

Please bid if you ar an EXPERT of Wordpress, Stripe, Pmpro and geolocation services.
