Have been using for 2 years throughout office and wouldn't change it for the world! Tried many, this one is the best! UPDATE: Two years later and STILL love this platform. Management is unmatched.

Trillion is great. Been using it for work for years on my computer. This phone app makes a good backup.

An excellent I'm, my one criticism being that enabling Text Formatting changes hyphen-space at start of line to a bullet point. I sort of see why, but I tend to start a line with hyphen-space when it continues the previous line, if you follow me?

I used Trillion when it first became available last century. If I consulted for a company Trillion was one of 4 programs I insisted on everyone uses whom I'd interface with. Is this APP similar to that or is it entirely new? Thank you

The latest version is such a downgrade in function and appearance. I updated in hopes of having the Klipy GIF picker, and now I have to deal with frustrating animations when sending messages, lag when typing, and unintuitive settings layout. It even forces reset my settings when I updated, blinding me with light mode (which I will never willingly use). I also can't use the built-in camera app anymore because it flashes the screen blinding white on capture.

Glad its getting updated. Keep it up if possible this is our fav messenger. Also happier with tje bugs being fixed now. So far its gotten better. Also if needed i jave info on how its effected our phones. Mine has problems launching from app button. It stalled out in black screen then restarted our phone partially. Then once it restarted and i re-did my screen lock (after being locked out when trill was restarted). It was working again no prob starting the second time but its always 2x to fix it

I used to love Trillion. Over the years they've added more features and, sadly, given up on reliability. For example, my son sent me a message that I received on my computer almost instantaneously and the next morning - 14 hours later - the message finally appeared as "new" on my phone. This is commonplace and messages are NEVER received on our phones with any rhyme or reason. We are now researching alternatives. Tril, you'll be missed, but not as much as the important messages I never received.
