Questions about this idea

Is Login Errors and Payment Disruptions a startup idea?
Not directly. These are complaints about a product or service people already use, and the fix belongs first to that provider. The page shows what is frustrating users and how badly — not an open market to start a company in.
How many people have this problem?
8 different people described it independently, in 8 mentions, the earliest from 24 Oct 2025 and the most recent from 18 Oct 2026. The quotes, with dates and links to the originals, are in the Evidence section.
Is this problem getting worse?
Status: steady — no change the counts can show. 1 people raised it in the last 30 days and 2 in the 30 days before; the status compares its share of everything collected from the same source, so collecting more or less cannot create a trend.
