The hacking issue remains a persistent problem, as the game lacks a proper anti-cheat system. Once you report a hacker, and if their account gets banned, they create a new one and continue ruining the experience for honest players, leading to an endless cycle. While the top leaderboard no longer features as many blatant hackers as in the past, that doesn't mean the issue is resolved. There has been some improvement over the last few years, but it's still far from perfect.
As for manager mode, it's essentially useless and has always been a pointless addition. All the resources should have been directed towards fixing the well-known VSA/H2H logic issues instead but here we are, part of the game where your input is irrelevant to the outcome. In the meantime, if you want to continue enduring the annoyances of MM, your best bet is to check out some guides, set your tactics, train your cards to max, and hope the game gives you a fair win.
