SharePoint 2016 Custom Tiles and intermittent visibility issues

[Rene Wagner]

I started playing with SP 2016 Custom Tiles and have (more or less) successfully configured an example tile that I was finally able to get to appear in the app launcher popout.  I do have a couple of questions, however:

I have noticed issues with newly added custom tiles not appearing to users ... I'm aware of the caching issue and running the ClearSuiteLinksCache() command -- but that typically does NOT resolve the issue.  I know it is not an access issue since the users I use do have access to the Custom List, as well as the site the list is stored under.  Also, I am eventually able to see the item after multiple attempts to connect to the site -- sometimes after clearing the browser cache, stopping and restarting the browser, it works -- other times it does not. 

The ONLY way I've found to get it to work more or less consistently is to force a browser logout and logging back in using the hidden SP URL -- this seems to be about 90% consistent in getting custom tiles to show up.

Is there some behind-the-scenes background process that is needed for newly added custom tiles to appear consistently and quickly?  Some job that maybe needs to run more frequently?

We've had issues like this ever since the waffle was rolled out. It works probably 80% of the time IMO. Supposedly some new announcements around this coming at ignite, may have to wait and see.

Thanks for the info.  We're seeing probably 30% of the time where it works ... ClearSuiteLinksCache() usually does not work, but it works sometimes.  Most reliable "fix" so far seems to be a forced logout  (although even that is not 100%)

Hi again -- I know it's been a while on this issue, but wondering if you've run across/heard anything else to get this working consistently?

Thanks.
