Bobby,
I don’t to think the Tuya/SmartLife integration plays nice with any platform. So switching platforms probably won’t help. I recently bought a used ST v2 hub for my 2nd location and I am currently using the Tuya app a lot less.
As JD said there are no Edge Drivers for Tuya WiFi devices and they are not needed because it is a c2c (cloud to cloud) integration.
As you probably know most Tuya WiFi devices don’t work with the Tuya-SmartThings integration. Tuya does not provided the firmware to make this happen unless the brand pays for it.
The work around for plugs, lights, switches, and other on/off devices is to create tap-and-run (scenes) in the Tuya app that turn the device on and off. You need 1 for On and 1 for Off. And for multi speed devices you need one for each speed. This might also work for IR blasters depending on how you are using them, but I have never tried it.
Once the work arounds are set up they are very reliable, but they problem is they are 1 way. ST can tell Tuya to do something, but Tuya will never update ST that a change in state occured.
In the past I found that the Tuya integration works better the SmartLife integration, so I use the Tuya integration even if I use the SmartLife app. This may have changed.
So even though your IR blasters have the ST integration, you could try the work around to see if it is more reliable.
The following provides more details on the work around. One change is that you can create the virtual switches using one of several Edge drivers.
