@rfc2822 Thank you for following up. The best way I could find to try to convey the feedback was to use their chat feature on their web page which unfortunately means I have no record of the conversation.
The representative tried to inform me about all the things I already knew, like how they supported so many calendars, how I am the only person to raise the issue etc., but after repeating myself a few times said they would provide the information to the developers.
I asked if I would get advised when/if the developers looked/fixed it but was told probably not.
So for now I can view the calendar in all I use except on my Android phone. That’s OK as not a vital thing, just frustrating.
If needed, this item can be closed. Thanks again.
Can't set sync to 10 or 5 minutes
Setting sync to 10 or 5 doesn’t stick. 15 and greater works fine. Experimentation indicates that the sync interval of 5 or 10 is not silently respected in the refresh rate.
Indeed. Android doesn’t allow that for battery saving reasons.
We had to remove 5 and 10 minutes as options because in recent Android versions 15 minutes is the fastest sync interval which is allowed by the system.
