Rich Text Title Style on Mobile

I have built a timeline using the widget in Flow. It does not display on a mobile phone. I have a Samsung Galaxy A71. Neither the timeline icons nor the content display when viewed on the phone. Is this a known issue?  

I have a video in my Flow course that has an uploaded .vtt file for closed captioning. It works great on a desktop, but there's no cc text option on a phone....just the transcript. Is there a setting to allow the cc text on a phone?  Thanks  

Has anyone had users report cc text not working on an Android phone? It works just fine on an iPhone. If so, other than having a transcript available, how did you resolve the issue? Thanks in advance

Seems like it should be quite simple but when the menu for "show" displays, the elements are rows and rich text. The icons I put on the graphic are not visible to select as trigger targets. Is there another method? (Markers do not work in my classroom environment.)

Is it just for navigation purposes, like "Click the icon to continue", or is it meant to display content that's initially hidden when the user clicks the icon? And if so, how does that work? If it's only for navigation, I think it's a little confusing to have it grouped with content-based interactive elements like Tabs and Accordions.

I'm creating a course with conditions: My stakeholders want to have a pre-test to partially test out of certain modules in the project (3 of the 8 modules with tests would still be required to be watched) and have test questions at the end of each module with a project pass score of 70%. The pre-test test out option wouldn't work in this situation since there are modules that are required to be watched/completed. I created variables for each of the modules that can be tested out of and set th...

Hi, I was wondering if there is a way to change the font style of the text within the pulldown box? So far I the answer and the surrounding text is taking on the theme font size, however the rest of the options seem to be significantly smaller   https://ibb.co/Q848NYR
