Cannot share multiple files from Whatsapp directly to Seafile with Seafile app

When i try to upload multiple files/pictures from an iOS device in whatsapp it only uploads the first file/picture.

So i go to Whatsapp open the Chat details → Media, Links,Docs select multiple pictures then share and select seafile pro as app.
After this i select the folder i want the files to be uploaded to. It now uploads the first selected file but not all of them

A workaround is:
Save all the picutres to the system fotos app an upload them via multiselect from there. This works fine

I encountered a similar issue and found a solution using WebDAV through third-party apps. Export the images to a file management app that supports WebDAV, then use it to upload all the images seamlessly.
