Problem with custom theme (JSON)
You are correct - JSON themes do not overwrite custom formatting options. You'll have Revert everything to default formatting if you want it to use the themes: https://docs.microsoft.com/en-us/power-bi/create-reports/desktop-report-themes#situations-when-report-theme-colors-wont-stick-to-your-reports
Good news is, you can use the Format Painter to copy formatting for many visuals (especially those of the same type).
Thanks for your answer. Is there a way to revert everything to default toghether? Or do i need to do this for every single visual and for every single format the customer changed? Or is your suggestion that I revert everything for one visual and then use the format painter to apply the reverted format to all visuals of the same type?
boeschr Unfortunately there's no way (that I know of) to revert all to default. I do know a lot, but definitely not everything, but from my quick web search I can't find anyone with a better solution.
There is an idea you could upvote: https://ideas.powerbi.com/ideas/idea/?ideaid=22249dc4-0034-eb11-8441-281878bda85b
Format painter is the quickest solution I can think of in the meantime.
Trick is really to teach people about themes early on so they don't run into this issue I guess.....
Thanks. I upvoted the linked idea 👍
I think it is easy when you start from scratch, but my customer had already started.
