Hey i wasn’t able to fix it but i made some hacky solution that work for me if you want to use. the only changes are made in TourGuideProvider.tsx change the if in setCurrentStep to enter the block only if the step order is one of thus in the scrollView also check step. i will note that there is very small dealy when going to the first element in the scroll but not something that seems to be a problem. for example my code look like this:

const setCurrentStep = async (key: string, step?: IStep) =>
    new Promise<void>(async (resolve) => {
    if (step && (step.order === 3 || step.order === 4)) {
        await step.wrapper.measureLayout(
          findNodeHandle(scrollRef.current),
          (_x: number, y: number, _w: number, h: number) => {
            const yOffsett = y > 0 ? y - h / 2 : 0
            scrollRef.current.scrollTo({ y: yOffsett, animated: false })
          },
        )
        setTimeout(() => {
          updateCurrentStep((currentStep) => {
            const newStep = { ...currentStep }
            newStep[key] = step
            eventEmitter[key]?.emit('stepChange', step)
            return newStep
          })
          resolve()
        }, 0);
      }
      else {
        updateCurrentStep((currentStep) => {
          const newStep = { ...currentStep }
          newStep[key] = step
          eventEmitter[key]?.emit('stepChange', step)
          return newStep
        })
        resolve()
      }

    })

if you have multiple tours you can add the tourkey to the if statment and adjust it so it work for each tour(didnt try this yet). after this i notice when i restared the tour i get an unhandle promise that stuck my simulator that is because scrollRef got undefined on the second tour i am gussing it because the poor handling of my part or something to do to the code structure to solve this i removed the if

if (!scrollRef) {
      setScrollRef(_scrollRef)
     }

to just

setScrollRef(_scrollRef)

this seems to work for me if you want to use it or have suggestions to make it better it much appreciated.

[nihatt]

i solved it by using multiple tour guides , but i am surprised tour guide doesnt work by only position . React should release a core package about it i think :D

[navaspavil]

@nihatt Could you fix it?

[nihatt]

@navaspavil yes , i used multiple guides.

[Drzaln]

and call next guides after the first guide is finished? @nihatt

[nihatt]

@Drzaln Yes , giving them each id's and calling them 1by1 helped me
