Any recommendations? These are the ones I’ve been using.
Innr Zigbee Smart Plug, Works with Philips Hue, SmartThings, Alexa, Google Home (Hub Required) SP 224 (2-Pack) https://www.amazon.com/dp/B07SQGG8Z7/ref=cm_sw_r_cp_api_fabt1_kJRRFbFS2CNBN?_encoding=UTF8&psc=1
If you like them, there's no reason to change.
I think they are working well, but I’ve also been seeing these issues so hoping they are not related to the routing devices! Always like to hear what other people like to use.
they are working as routers (if those are the Innr units), you can see them in your route table
Cool as long as all routers are created equal! 
Definitely NOT what he said. The ones you are using are probably fine; not the best, but priced appropriately.
Ok so which ones are the “best”?
In my experience, the Samsung SmartThings Smart Outlet is a really good Zigbee repeater.

I have 5 of these and they are excellent. Stronger signal and repeat for more devices than others I have tried.
Problem is that they have been discontinued and sellers that still have a few have doubled the price, so unless you find them on eBay or Craigslist. You will need to find an alternative to that one. I use the Ikea plugs (not the actual repeaters) because they have a very strong signal and work well, but they are a lot bigger than the Samsung ones.
I would say Xbee3 pro
they will allow you to route more end devices (12-20 depending on model) VS an average router device (7-11) and you can map your zigbee network.
If you don't dislike the look, you could get the Ikea outlets. Super cheap, and work very well. They are just big and ugly.
I replaced all my ikea outlets/repeaters with below to keep the Mrs happy. They also work well:

Doubt that and look at the description, it says WI-FI, I don't think that will work as a Zigbee repeater!
If you can still find them, the Iris 3210-L2 smart plugs make great zigbee and z-wave+ repeaters.
I think this is a big thing I was missing. I know the HE can do up to 32 devices and I knew you had to add routers, but I thought each router could also do 32 so I figured I was fine. From what I'm hearing, routing devices can really only handle 10-20 which makes more sense why certain devices are failing randomly for me!
I usually limit each router to 6 devices. Gives them a little headroom if things ping pong around.
That's for a different model, which is why it says "view newer model". It's only showing the bottom of the page from my screenshot since that is all that would fit.
I have one of these Centralite plugs which seems to work quite well in my garage, repeating sleepy devices.

innr are zigbee 3.0 so in theory they should be some of the better ones you can get.
i certainly wouldn't buy anything that isn't 3.0 anymore.
