I've been testing the expansion with early access, and since then any of my Sims, in any save file, lot type, business field, cannot go past rank 2 of the renown.
At first, I thought I was not executing all the necessary interactions.
Then today I tested again and I paid attention to every detail, like the "headline-effect" feedback of the customers (happy emojis), green renown icon on the owner head with +++, positive moodlets about being happy of staying close to happy customers, and so on.
But the bar never increased, and the end of the business day, 0+ points were added to renowned rate, according to popup window.
What made me think it was a bug and therefore search for a bug thread in here (couldn't find any), was that I tested with a cheat to increase the ranking, and the cheat only worked for rank 1 and rank 2. Ranks 3, 4 and 5 did not.
I usually play with MCCC mod + UI cheats mod.
I tested without mods, still it didn't work.
I repaired the game and tried on a new save file, still didn't work.
I play on PC/EA App (launching through Steam).
Let me know if screenshots/videos are needed.
