You can't do much on a watch-only wallet; all you can do is to make an unsigned transaction and broadcast it, plus it consumes large resources, like it needs your core to be fully synced.
If you don't have a full node, Armory won't function properly.
You better switch to a much lighter version if your purpose is to use it daily. Electrum would be a good option.
I tried to export the private keys from both wallets with armory offline. It hasn't synced up to the network in years. Will that be a factor?
Exporting private keys doesn't need an online network to be synced. Exporting any sensitive keys offline is a must because if you export it on a PC connected to the internet, you are vulnerable to online attacks. So avoid exporting keys when online.
