Diagnosis
The projector's Wi-Fi radio is weaker than your phone/laptop, or there's a software cache issue with the streaming apps.
How to Fix It
Clear the app cache and data. Go to Settings > Apps, select Netflix/Disney+, then choose Clear Cache and Clear Data. Log back in. This forces a fresh app install without deleting it.
If That Didn't Work
Improve your Wi-Fi signal. The Freestyle 2's placement matters. Move it closer to your router, or use the 2.4GHz network for better range (sacrificing some speed). As a last resort, a USB-C to Ethernet adapter with a wired connection is the most stable fix.
Heads Up
Avoid placing the projector in a media cabinet or behind a TV—the metal and electronics severely block Wi-Fi. Give it a clear line of sight to your router.
