Gallery shows lists sometimes

My SharePoint list is over 8000 items. Just recently, the gallery in my powerapp will sometimes show the list of entries and sometime it won’t list anything. This apps has been up and running for over a year. I published the last version and it still does the same thing. I have a team of 15 people who use this gallery throughout the day and it’s affecting our productivity. I’m stumped. Anyone have any suggestions? Thanks in advance 🙂

It maybe a Data Source connection issue? This post describes how you could attempt to fix this, ie

- remove the Data Source

- re-add the Data Source

- re-reference any code that uses that data source eg Patch(), etc

 

This seems an unusual fix because I've never encounter this but it may work. 

 

The only other thing I could offer would be to check network load. You mention one field that looks up another List and if your gallery needs to process many of these at once it can slow render time - I've seen this happen before.

You need to be more descriptive about your issue. Info that would help include:

 

- Items property of the gallery

- any delegation warnings 

- devices using you app, eg all desktop/laptops using LAN or mobile devices using 3G/4G or a mix of these

- which devices are having issues, eg on mobile devices 

- network load of your gallery, eg do you have an image per line item that does a look up to a Library ?

- labels in the gallery that lookup to other lists/libraries

- anything else that maybe relevant

 

Its a little hard to give advice without any of this, and other , info.

@EddieE - Thanks for replying. I hope my answers below are helpful. I appreciate you helping 🙂

 

- Items property of the gallery

Jaybird2564_1-1649076479280.png

 

- any delegation warnings 

None - I only use Text to filter and there are only 4 "Starts with" in my gallery items property. 

 

- devices using you app, eg all desktop/laptops using LAN or mobile devices using 3G/4G or a mix of these

All laptops using LAN

 

- which devices are having issues, eg on mobile devices 

Team Members always use Laptops. However, I can pull up the app on my Iphone and iPad. When the gallery stops working, it stops working on all devices. 

 

- network load of your gallery, eg do you have an image per line item that does a look up to a Library ?

No images, Its all "Thisitem." from the SharePoint list. 

 

- labels in the gallery that lookup to other lists/libraries

Just 1 "Choice" field from another list and its been in place for several months. 

 

- anything else that maybe relevant

The weird thing is the gallery populate sometimes. Its sparactic throughout the day. Below is a picture of my gallery.

@Jaybird2564 

Could you please repost your Items property in a Code window (<\>) - I cannot read your image. No need for sensitive info, just the structure

 

Its a fairly jam packed gallery but that should be fine on a LAN network 

 

EDIT: Never mind about reposting the Items, I can see it fine on my desktop. I tried reading it on my phone and it just washed out 🙂

@EddieE - Thank you so much for helping. You are spot on. After working with my IT guys, this is a SPO connection issue. That type of issue is above my pay grade; I just know how to build the apps. Again, thank you for your help and have a good one 🙂
