SARS eFilling, the worst app

SARS eFilling This app isn't user-friendly at all. I tried submitting 2021 returns, only to find already installed RIP5 with wrong details, worst of all, I wasn't given an edit option. At first I thought it was because I'm using mobile app, so I went to an internet Cafe only to encounter the same problem. So I had no choice but to submit the information already on the system. I don't know what will be the consequences of that.
