Possible Scam.
Some shady apps do exactly what I stated above: let you in briefly, then push you to a higher price point, hoping you’ll give up and pay.
Response from developer
Hello, and thank you for your feedback. We sincerely apologize for the inconvenience you’ve faced with the subscription. This is not intentional or a scam — the issue is due to a temporary technical problem with the annual plan, which is currently unavailable for all users. As we’ve mentioned in our email, you can request a refund directly through Apple, and your money will be fully returned. In addition, once Apple approves our new monthly subscription, we will send you a promo code for one free month as a gesture of apology and appreciation for your patience. We truly regret this situation and are working hard to fix it as soon as possible so it will not happen again in the future. Your trust is very important to us, and we would be grateful for the opportunity to make things right.
