### 1/5 — Misleading and waste of time

*2023-10-09*

I responded to an advert on instagram that this App can do instant transaction using AI. Within 10 minutes I deleted the App as it’s plagued with annoying advertisements that are not relevant. The App is keen to track any activity on other Apps. What a waste of time !!!
