Hi, I’m new to build and app. It’s my first time doing it and I’m facing some problem.
So I have several links on my app. I put the link on the “Rich text”, so it’s doesn’t need the block (right?). This is the link on rich texts I’m talking about (the blue one):
When I click the blue link, it say, “Don’t know how to open this URL”:
But I can open the link by clicking it in other phone 
Is it a phone problem? Like, is it because of my phone? Not my app? Because I can’t open it on my phone, but I can open it from another phone. Both of the phone are android.
Anyone can help me, please?
And, sorry for my bad English, it’s my second language.

What is the link that is not opening correctly for you?
Hi matt thank you so much for answering.
It’s just some pictures link I got from Google

I tested your url as rich text and it worked for me. Check the blocks I used and preview it on a computer and mobile device to see if it works for you.

(See the first screen)
I was able to open it as well so it is likely a browser permissions or settings issue on your device. You may want to see if there is not a different app selected on your device to handle opening .gif files.
Thank you so much Tati 
It works now
