Spotify Struggling on Sony Walkman NW-A306

[Mindorra]

I previously had a Sony Walkman NWA-105 which I used exclusively as a dedicated music device for stored music on the default app and Spotify. It was getting a bit slow at times as the memory was quite full, and then I dropped it in the bath (doh) so having been broadly happy with it I decided to replace with a newer version, the 306, with more memory.
I'm having nothing but problems. It's brand new out of the box, running Android 13, Spotify freshly installed so there shouldn't be any broken registry issues or whatnot. I've disabled a lot of the non-essential default Android apps (calendar and maps and whatnot) so there's no significant background usage and battery saver is switched off. However whenever it's downloading music (which I've been doing a fair amount of during setup) it's incredibly unresponsive regardless whether I use the side buttons or touchscreen, and has a habit of crashing. It also seems to be struggling even when it's NOT actively downloading. The downloading itself also seems incredibly slow despite my internet connection being good - I do have a significant library, but I was not having this level of issue with my previous device even WITH low memory and water damage! It's especially frustrating when you need to pause or stop something in a hurry and simply can't, or tap the wrong thing and have to wait 10 seconds plus for it to load so you can go back to where you were (waiting another 10 seconds or so and hoping it doesn't stop responding completely in the meantime).
It doesn't seem to be the device itself as I don't have issues using the default music app, so it's either Spotify itself or the interface of Spotify with the device.
Any help (that's not uninstall and reinstall) please?

Hey @Mindorra,

Thanks for reaching out & sorry to see you've been having issues with the app performance!
Let's try a few things to hopefully resolve these issues for good 🙂

1. If the app is installed on an SD card, it might be a good idea to move it to the device's internal storage.
2. After this is done, open the app and let it download all offline items. 
3. If the issue continues to persist after all downloads are complete, try switching the High-Res streaming Walkman option off. To do so:
   1. Swipe the [WALKMAN Home] screen upwards.
   2. Tap the menu items in the following order. [Settings] － [Sound] － [High-Res streaming].
   3. Tap the switch to turn the [High-Res streaming] function off.
      
      

Hope this helps! Keep us posted on how things go 🙌🏼

Thank you.
The app is installed on the device, but downloads are stored on the SD card (and moving it to or having it on the device would be incredibly limiting and kind of defeat the purpose). High Res streaming isn't / wasn't / hasn't been switched on. 
I'm hoping it's just the sheer volume of initial downloads and setup stuff but I'll do some testing in the next couple of days. I tried getting in touch with Sony to see if it's a known issue with device performance but they were less use than a chocolate teapot!
