Hi there! I see that the NIIMBOT app doesn’t show up in the Play Store on your other Samsung tablet, even though it’s the same Android version. Let’s work through this together.

To start, could you tell me:
- The exact model of the Samsung tablet where the app shows up vs. the one where it doesn't?
- Have you tried searching for the app through a web browser on the tablet’s Play Store (play.google.com) instead of the Play Store app itself?
- Is the Google Play Store app updated on the tablet where the app is missing?
- Are you logged into the same Google account on both devices?

Often, apps might not appear in the Play Store search if the device is seen as incompatible due to model restrictions, region settings, or Play Store cache issues. Here are some steps you can try:

1. Check Google Play Store Updates and Cache:
- Go to Settings > Apps > Google Play Store.
- Tap Uninstall updates (this will revert the Play Store to its original version).
- Then open the Play Store app and it will automatically update.
- Clear the cache from Settings > Apps > Google Play Store > Storage > Clear cache.

2. Check Device Compatibility via Browser:
- On the tablet where the app doesn’t appear, open a browser and navigate to the NIIMBOT app page directly (NIIMBOT on Google Play).
- Log in with your Google account and see if it says “Your device isn’t compatible” or if you can install from there.

3. Region Settings and Account:
- If the second tablet uses a different Google account or is set to a different region, the app might be restricted.
- Verify your Google account settings and regional preferences.

4. Reboot the Device:
- Sometimes a simple restart can help Play Store refresh device compatibility information.

If these steps do not reveal or solve the issue, it might be that the Play Store is filtering the app due to hardware or model-specific compatibility. Some Samsung tablets, even with the same Android OS version, might not be supported by certain apps. This was noted by users who experienced similar issues with older Galaxy tablets1.

Could you please try these and let me know what you find? That will help me guide you with next steps.
