On mobile view you cannot scroll down

[szaimen]

Steps to reproduce

1. Install the Task app from the app store, open it and create a few tasks.
2. Login on my mobile phone with the "Brave" browser (which is based on Chromium).
3. Now I try to scroll down.

Expected behaviour

Should be able to scroll down.

Actual behaviour

Not able to scroll down because the task I am currently touching is just moved.

Duplicate of #421.

[szaimen]

Thank your for referencing. The thing is, that this issue should get fixed with version 0.11 and I am already running this version on my nextcloud but it also does not work with this version.
So please reopen the issue.

[raimund-schluessler]

@szaimen Please make sure you don't use a cached version of the app. Clear the cache of your mobile browser and reload the Tasks app.

It works fine for me with Safari on iOS12. We use a delay of 500 ms. After you touched a tasks longer than this time without moving your finger the dragging starts.

If the issue really persists for you, please fill the complete issue template. Otherwise I won't be able to reproduce your problem.

[szaimen]

Done!

[raimund-schluessler]

@szaimen Thanks for filling the issue template.

I tested again on iOS12 with three different browsers (Mobile Safari, Chrome and Firefox) and it works well for all of them. However, on a borrowed Android device (Samsung A3, don't know which Android version it runs, probably a really old one) I can reproduce your issue. Dragging sometimes starts, sometimes it kinda works.

However, this is an upstream issue in the drag-and-drop library we use (Vue.Draggable, which itself uses Sortable.js). So we cannot fix it ourselves directly. There recently was a fix SortableJS/Sortable#1517 for the delay option in relation with Android, so it might be fixed with one of the next releases of Vue.Draggable.

[raimund-schluessler]

@szaimen Could you please check that the issue also occurs on this minimal example: https://codepen.io/raimund-schluessler/pen/EBRxdz
I would like to report it upstream to Sortable.js.

[szaimen]

Yeah, I tested your example and the issue also occurs there - every time.

[szaimen]

Thank you for reopen!

[raimund-schluessler]

I reported the issue in SortableJS/Sortable#1556

[szaimen]

Thanks!

[raimund-schluessler]

The issue should be fixed upstream now, but it will take some time until updated releases of the libraries are published.
