Hi @eddeee888,
Do you have any updates on this issue? Since dedupeFragments was removed, I'm wondering if there's an alternative solution available or if there's a fix planned.
Thanks!

Hi @ItaiYosephi , I'll take a look. Sorry about the delay 🙏

Hi @ItaiYosephi ,
Sorry this is a bug that I missed! The intention is to enable the behaviour by default, instead of removing the config option and the behaviour.

Here's the PR to fix that: #10554
