I wanted to juggle multiple point-earning apps (a failure story)

Both PoiMu and MiruPo apps involve leaving unused apps idle for up to 3 hours, watching video ads upon completion, and sometimes watching ads at the start as well. You get 100 points for idling one app for 3 hours with ads, and the exchange rates are 11,000 points for PayPay and 13,000 for Rakuten. Initially, you could run 5 apps plus an additional 3 simultaneously, so I thought it would be easy and decided to try juggling them! However, even though I was running them separately from my previous smartphone data, perhaps due to SNS linkage causing a conflict, I ended up with points accumulated but unable to redeem them due to an error. They said SNS linkage cannot be removed. It's easy to earn points if you use it well, but this really dampened my spirits. Everyone, please be careful.
