Update On The Matter
As of today, it got fixed on its own after not working for a long while now. Coming back to read the replies and then checking the app, now it finally lets me log in and actually use it unlike before without me doing anything extra. I just placed my info as normal and usual and got in. I don't know what the problem was or if it'll happen again but keep an eye on it regardless. So far it seems to be working just fine on my end but I don't know for how long that'll be though.
I'll update this reply post if something occurs with an edit note if I have something new to bring up. I still hope that they look into though and soon because I'm not the only one who was affected by this issue that shouldn't happen if we can log in just fine to the browser version.
