'Input Number' inc and dec buttons missing

Where there’s an input field for an ‘input number’, there used to be little up and down arrows appear, when the cursor hovered over the number box, to enable increase or decrease in value.
They’ve now gone, but I don’t know when it happened.
I have installed UIX recently, but also updated core to 2026.4.0 and Supervisor to 2026.03.2

Core 2026.4.0
Supervisor 2026.03.2
Operating System 17.1
Frontend 20260325.5

How are you displaying the input ? Tile card with feature?

Do you have a theme enabled?

There is no theme configured / enabled.

The single display above is an entities card on a dashboard with a Sections layout.
Those shown here are on an entites card on a dashboard with a Masonry layout.

I’m sure they all had in/dec buttons before.
But, before what?

Browsers used are Vivaldi and MS Edge.

I just noticed this too, I think it’s 2026.4 that has done it.

I have the same problem with 2026.4. I have several input_select, input_number, input_datetime, and input_text values on entities cards. I am using IOS Themes. All the input areas are now blocked in white instead of my theme colors. The displayed text is black during the day and white at night (basically invisible).

I use IOS-Themes and I found the following, which may help with figuring out other themes: https://github.com/basnijholt/lovelace-ios-themes/issues/102
He added the following parameters to the theme:

Same problem here, no arrows in input number fields.

I’ve updated everything now:

Home Assistant OS
Core 2026.4.2
Supervisor 2026.04.0
Operating System 17.2
Frontend 20260325.7

As my Rpi 4 was an early version, I also did the bootloader update. Bootloader was Sep 2020. There were warnings about a possible loss of USB booting if the 17.2 OS was loaded. I’ve no idea what version it is now, as it didn’t say what was being installed during the update process. It doesn’t show during bootup now, either. Just a bright red raspberry pi screen.

There’s no change to the missing inc/dec buttons. They’re all still awol.
Also noted, the login text is invisible when using dark mode in a browser. It’s dark text on a dark background. I guess it’s just another screw up from one of the updates.

Thankfully, it’s not significant enough to worry about. Maybe the buttons will make a comeback, one day. As a ‘feature’.
