Your Calendar Widget - https://play.google.com/store/apps/details?id=de.mash.android.calendar
Open the Calendar app, go to Settings, then tap on a calendar(s) that you want (may have to tap Show more to see all calendars) and make sure sync is turned on for each one. I use a different app for my calendar widget and each calendar has to have sync on for the widget to see the events.
If it still doesn’t work, maybe try removing your Google account entirely from your phone and re-adding it.
I literally just bought this laptop for $1k, Eluktronics RP-15 15.6" RTX 4060 Gaming Laptop AMD R7 7840HS 16GB RAM 512GB SSD. It just arrived yesterday, so haven’t had much time to test it out yet.
Agreed, I haven’t been able to find one launcher that has all the features that Nova has. Neo is close, but still doesn’t have swipe on dock icons, you have to choose either tabs or folders in the app drawer, you can’t do both like you can in Nova.
