This is absolutely ridiculous what’s the tips on getting a test ?

This is ridiculous I tried putting Jan 2026 and still no tests??? Is there a glitch there’s no way everything is booked….. my gf this time last yr was able to book a test for March and there was slots available….. what’s your tips and hacks to this please, also do you need to have a test booked to use Testi and other apps ?

Thank you I appreciate it
