Long Duration between publishing and update in builder

Hi, we have the issue that often times our updates take very long to be reflected in production after “publishing”.
That especially happens for value which are used with data binding and used outside builder, but also components in builder.
Sometimes up to 30-40 min.
What could cause that? What time is expected?

Also it then happens that some value seem to be updated and other seem to be cached when refreshing and stay with the old value. That doesn’t really make sense for us. When deleting the cache all value are updated (but very delayed)

@wissem.yahiaoui What is your tech stack? May we see the portion of code where you have integrated Builder for this page / project?
