@Yarbo-Forum My firmware was updated this morning to 3.9.29 but the updated Android app is not available in the Play Store. When will that be available?

iOS app isn’t approved yet either.

Any details on “* General performance enhancements and stability improvements”? These are the ones that worry me.

Great news!

No update yet on my Yarbo. Looking forward to seeing the improvements!

So we took the easy way out and only made it a global setting. The pathetically slow speed while traveling down minimal slopes to and from work areas remains - even when the blades are off and there’s no need to worry about missed grass areas.

I’m sorry, but we currently do not have a clear timeline for Tow Mode. Our R&D team is focused on developing key features such as the dead reckoning algorithm and visual inertial odometry. These are critical projects aimed at improving the overall performance of Yarbo. Due to limited resources, we’ve had to reschedule the development of Tow Mode.

We truly appreciate your interest in this feature and have shared your strong desire for it with our product team. Thank you for your patience and understanding as we continue to work on refining the product!

Have you been able to get the app update now? It should now be available on the Play Store.

No worries! This description covers some minor optimizations in the app, such as fixing the occasional white flash issue during the initialization of the second step on the prepare data center page.

Support center link leads tho knowledge base, no way to view current tickets.

This is what I get now… even when I pick feedback after taking a screenshot.

A little nitpicky but Slope Management is named “Adaptive Ramp”. I think something happened in the translation :slight_smile:

I have the latest version on android but I do not have that option. There is not thing after the rain sensor.

Manually check for the update in Google Play. I just looked and the Android update is available, in the US as least.

Yep. Something is broken. This happens in the iOS and Android apps. Going to website directly still works. Support → Help Center → Tickets.

The app updated overnight.

Using Android 3.15.5 when I click Suport Center it lists the link to the KB at the top and if I scroll down beneath Submit a Ticket is My Recent Tickets and all my tickets are listed.

I have the latest version, playstore and yarbo app say so. No slope toggle for me, but I don’t need it.

That’s odd. You are looking in Settings → Working Preferences I assume. I know you don’t need it, but something isn’t right. Maybe an full Unistall/Reinstall if you feel the urge.
