is there a reason why it updated the map before it could finish map data processing? is this a bug? ![image](https://us1.discourse-cdn.com/flex015/uploads/mapillary/original/3X/3/e/3eba2f59db4c51f171feb0ccbf2e8026f79d0b31.png) ---

I also see this happening sporadically for _some_ of my uploads. Is is it considered normal that the Map Data Processing happens after the Map Update? (And if so, perhaps the order of the Map Data Processing and Map Update ought to be changed to avoid confusing us users šŸ˜‰ Examples: Sequence key E2CvdZs5lF7NPQBWYV964g [Link](https://www.mapillary.com/app/?pKey=1722359171849705) 3 Aug 2024 ![image](https://us1.discourse-cdn.com/flex015/uploads/mapillary/original/3X/0/1/013dee141d914bce728f307e432c5921e5d3ce5a.png) Sequence key AGMqxg6orchbTZUN0KQ4dv [Link](https://www.mapillary.com/app/?pKey=1251830452846426) 3 Aug 2024 ![image](https://us1.discourse-cdn.com/flex015/uploads/mapillary/original/3X/b/f/bfee656611f68e1b67fd6864b9bb3c995824f7f4.png) Sequence key wtk48ifz2lLmIQx3BFoZ7v [[Mapillary](https://www.mapillary.com/app/?pKey=1034342430933241)] 3 Aug 2024 ![image](https://us1.discourse-cdn.com/flex015/uploads/mapillary/original/3X/3/4/34d0d9a5b1d1916bdca7fd50e305bdcc267e0ee7.png) Sequence key COFfm29vQanXiHNLhrSMtK 3 Aug 2024 ā€¦ Sequence key INTGD1tpwBP0vA7sR8hzYl 31 jul 2024 ![image](https://us1.discourse-cdn.com/flex015/uploads/mapillary/original/3X/5/4/54208eb8227a9e4fba12d5b3a0260f13f5649ff9.png) Sequence key yTAGScu5EZhwev0VU4PrgQ 31 jul 2024 Sequence key cS6KIteCR20XsfkDmQorGT 31 jul 2024 Sequence key H8JODob3FywfsYZ5l2pm6A 31 jul 2024 Sequence key IXUN4DQiHz8J6hvldp7jPO 31 jul 2024 ā€¦ Did not find any sequences in this state in the contributions between 30th of July and 19th of June, so Iā€™m not concerned about it.

Thanks for reporting @brunofilmklov seems unrelated to the issue [Delay in processing [2024 August]](https://forum.mapillary.com/t/delay-in-processing-2024-august/8300) Iā€™m looking into it - will keep you posted. Feel free to tag me directly for notifications and apologies for the inconvenience. ---

Hey @brunofilmklov, Thanks for being such an active user šŸ™‚ I skimmed through all of your older imagery and it seems that now everything is processed right? Let me know if you see it otherwise. Thank you so much! Kind regards, Balys ---

Yes, it is now processed, thanks for fixing the issue. However I think the original question remains unanswered: is the ā€œMap Data Processingā€ supposed to run _concurrently_ with the ā€œMap Updateā€ step ? ---

Hey, Sorry for the delay in responding! šŸ™‚ The `Map Data Processing` and `Map Update` are both a collection of data processing tasks in the backend. `Map Update` is dependent on one of the underlying tasks in `Map Data Update`, so it launches always afterwards and usually finishes afterwards, but technically they can run concurrently. In practice, most of the time `Map Data Processing` starts and finishes before `Map Update` and although they can run concurrently, it usually indicates an issue or a non standard flow. Does this make sense? Kind regards, Balys
