App for Android wrongly deployed for ChromeOS: breaks usability of spreadsheet app on ChromeOS

[flagellatedcucumber]

Collabora app for Android (e.g. v24.04.7.3 running on Android v8) works normally as a spreadsheet on an Android device.

Collabora app for ChromeOS (e.g v24.04.7.3 - the same app - running on ChromeOS v130.0.6723.216) works abnormally as a spreadsheet on a ChromeOS device with an integrated keyboard.

On an Android without keyboard - i.e. with a glass screen for which the sole input from the user is finger-poking - the app works. It is designed to depend on finger-poking to enable/active the on-screen keyboard for user data input. This is appropriate for a glass-screen finger-poking input.

On a ChromeOS device, with its own integrated keyboard, the app wrongly behaves the same way. So the user of a ChromeOS device needs to click the mouse in every cell and/or edit box before being able to type anything. This is a ludricous design choice. Specifically, the user needs one hand on the mouse and one hand on the keyboard, resuling in single-hand typing (akin to finger-poking). The outcome is that the app is functionally unusable on a ChromeOS device, or any device with a physical keyboard.

The design objective for Collabora on ChromeOS must return to useful functionality. The app needs to be ready for keyboard-only user input, ready for cell editing, just as any user would expect with LibreOffice or MS Excel on Linux/Windows/MacOS.

Steps to re-produce on ChromeOS with an integrated keyboard:

1. Launch Collabora
2. Create new sheet.
3. By default, the sheet is now in read mode (as would be appropriate on Android).
4. Click on the edit icon.
   Fault 1: there is no objective need for an edit icon on device with integrated keyboard. The app should be in edit-mode by default, just as LibreCalc/MSExcel would be.
   Fault 2: there is no keyboard access to the edit icon.
5. Without moving the cell selected, try typing.
   Fault 3: no text appears.
6. Use mouse to click into formula bar.
   Fault 4: the user needs to click the mouse into the formula bar. Utter waste of the user's time.
   Fault 5: no keyboard access to the formula bar. In LibreCalc/MS Excel, F2 would achieve this.
7. Try typing. Text now appears in both edit bar and selected cell.
8. Hit enter to close the edit of the cell (as would be required in LibreCalc/MS Excel).
9. Use the tab, return and/or direction keys to move the selected cell around the sheet. Reapt steps 7-9 until the machine ignores all further keyboard entry.
   Fault 6: the machine will eventually give up accepting keyboard input.
10. Whilst in edit mode, use SHIFT+DOWN etc to select a range.
    Fault 7: cursor doesn't always move, so a range is no longer selectable by keyboard.
    Fault 8: CTRL+D - which should be fill-down - does not work.
    Fault 9: CTRL+C, select range (by keyboard), CTRL+V does not work. Where CTRL+C and CTRL+V do occasionally work, it is for single cell copying only.

The assumption that AndroidOS = ChromeOS is a false assumption. The environment, and its peripheral IO devices, are different. Deploying the false assumption breaks the usability of the app on ChromeOS.

At this point, I gave up. Please let me know when Collabora for ChromeOS is entirely keyboard-useable, and I'll have another go.
