Bug in TAP system?

Wanted to check if anybody else is facing issue with the app recently? I have been noticing few glitches over the last month or 2. My app version is up to date. Pic upload seems to be worst affected. Sometimes I don't get the option at all or don't see the pic I uploaded in the pic gallery while browsing. Stickers never work for me so I just ignore them. Some of the links seem to be broken or leading to page not found. Aside to this, rewards redemption is also affected. I redeemed at least 3-4 rewards which shoul've arrived by now, even by normal post but they haven't. It's been more than a month for at least 2 of them. Going to be shifting house soon so wondering how long it's gonna take? Anybody having similar experience?
