Unable to upload *.IMAGE in iOS app (2.25.5)

Expected behaviour

Use the share option in Time Stamp Camera, Select Nextcloud, see *.Image selected in nextcloud app (then procede to create folder and save files)

Actual behaviour

Use the share option in Time Stamp Camera, Select Nextcloud, don't see any files (*.IMAGE) I want to upload

Steps to reproduce

Use the share option in Time Stamp Camera after having selected 1 or more picture, Select Nextcloud,

Reasoning or why should it be changed/implemented?

Working with the same Nextcloud server, Version 2.24.1 of Nextcloud IOS app, (Not updated version on Teammate Iphone)
Able with 2.25.5. to upload files that are not .IMAGE
Able to share files with Time Stamp in same format (.IMAGE) through One Drive app. (on other server)

iOS version

12.4.1 and 13.3

App version

2.25.5

Server configuration

Dont have currently acces to server infos but can send files with same version of Time stamp camera and an older version of Nextcloud.

Start by reproducing the share flow from Time Stamp Camera on iOS 12.4.1 or 13.3 with Nextcloud 2.25.5, using files with the reported *.IMAGE format, and compare it with 2.24.1. Done means the files appear in the Nextcloud app's share flow so they can be added to a folder and saved.
