Tried to save a fairly complex 11 mile route, kept getting the error in attached screenshot. Tested saving a random route on my laptop and worked fine, so redrew it and that also worked fine: https://citystrides.com/routes/5331. Problem exclusively on mobile.
Strange! I couldn’t reproduce this. The next release will include more information in the error message popup(s) - hopefully that gives us a clue. Keep an eye out in #announcements for the next release just in case I forget to mention it here.
