TextMesh Pro Mobile input still present despite being toggled off on TMP Input Field

Hello!

I am working on a project in Unity 2020.3.6f1 targeting Android and iOS. This same issue was present when building with 2019.4 LTS as well. I am using TMP version 3.0.6. The problem I am experiencing only occurs on Android.

My TMP Input Field has "Hide Mobile Input" checked. When I tap the Input Field on an Android device and start typing, the Mobile Input box is physically present in the scene despite being disabled. If I tap where I would expect it to be, the keyboard is not minimized, and the cursor jumps around as if it was enabled. If I gradually move my finger higher in the screen, the app regains focus and the keyboard disappears.

I have attached the settings on my Input Field, as well as 2 screenshots in the actual app.

One is using the default keyboard. Here, the mobile input is invisible, but still present.
In the second, I am using a custom Fleksy keyboard (Version 10.2.7 (3376), if it is relevant). In this instance, the invisible text in the mobile input is underlined, and grows and shrinks as I type/erase.

To reproduce this issue, I created a new Unity 2020.3.6f1 2D project. I added a canvas set to shrink to a screen size of 800x600, and added a TMP Input Field as a child of the canvas with the attached settings. Then I built to my device.

The devices I have tested this on:
Samsung Galaxy S20 5g
Samsung Galaxy Note 8

Ideally I would like to hide this completely. If any additional information is needed please feel free to ask.
Thanks in advance!

 

Unfortunately, I haven't had any success in resolving this issue. I've tried updating to 2020.3.8 with no change. Any insight as to why this may be happening would be greatly appreciated.

Edit: I see now from this page that the mobile input hiding is only a visual effect. Is there any way around this? When building using 2019.2.9, this issue was not present. It wasn't until I updated to 2019.4.21 that I started seeing it.

 

Assuming this being fixed for Unity will fix it in TMP as well, then this page is the solution to my problem.
