The markers ^ button on S1 remote that allows you to choose timeline markers does not function in S1 v5.
Tested the current IOS and windows versions of studio one remote. Confirmed on windows tablet and apple ipad, that the markers don’t even show on either the windows remote or the IOS versions on the timeline, and the ^ button doesn’t function.
Tested on S1 v4 and button works as before. Conclusion: S1 remote has a compatibility issue with S1 V5.
