Chrome - Firefox problem
So when I add or change something in Chrome, it doens't show in Firefox.

Please give some examples.
What added or changed.
Where added or changed.

When I do it in Firefox, it won't show in Chrome.
Is this a problem I can fix or do I constantly add it 2 times?

In the website interface this cannot happen.
Something is wrong.
Some changes or additions, when requested by API Request, may take up to 8 hours to become available.
Please post here a link you used that had a problem with not being updated.

Thank you for the quick response.

It's about a Dutch documentary series: https://www.themoviedb.org/tv/82137-pano/season/1
So I added a description in Chrome for each episode but it won't show in Firefox (the images did change on both browsers).
Season 7 and 8 I tried it in Firefox and won't show in Chrome, so later on I re-added it in Chrome so I did it 2 times.
So now I only work in Chrome because that seems more stable

So when I add some text on one browser it won't show on the other one.
When I open TMDB on Edge or Opera, everything is fine and it shows the description so maybe it has something to do with Firefox?

My initial guess is that it must be your browser's cache memory problem.
But I went to check the edits you made and found that they were made in two different language-COUNTRY.
Dutch; Flemish (nl-BE) - "Dutch - BELGIUM"
Dutch; Flemish (nl-NL) - "Dutch - NETHERLANDS"
Maybe that's the problem.
In Firefox it is using a language-COUNTRY and in Chrome it is using another language-COUNTRY.
Please check and let me know.

Thank you, it was indeed the language-country. I was using Dutch-Belgium for Chrome and Dutch-Netherlands for Firefox and didn't saw it. I now added everything in the 2 languages but will better look out for in the future. Sorry for the inconvenience
