I have another potential work around that worked for me. I setup Authy in an Android Emulator called Genymotion. It is naturally rooted (I had already installed Authy a while back, so I don't know if it can be installed now - but I will check on that when I am ready to delete Authy, and try to reinstall it). Within the emulator, I installed Aegis and imported the Authy codes. From there I exported to any app of choice like Ente, or keep with Aegis. However once on Ente, it can sync to your other devices right from the emulator.
The emulator is good to have on your PC as another way to access the synced codes without needing your phone (since many of these apps are only mobile apps and not web based or work on PCs).
