Yes, you shouldn't have a problem, I've been a user of Coinomi for a long time ago, and AFAIK, even with which wallet address you will open default, legacy, or compatible it should appear on your balance there, any kind of address you have.
Even though you will send Bitcoin on Legacy and send Bitcoin in Compitable address, you will see your full balance.
The reason I leave that wallet a long time ago the time I knew that it was a close-source wallet which is not good IMO. Still, open-source wallets which make me confident in storing my Bitcoin even if that's a hot wallet.
This has also been one of my problems with some other wallets. When I was still new to crypto and didn't know which is legitimate and not, I was exploring and trying different crypto wallets to find out, and after time went by, this has become a major issue for me. Glad to hear it could be resolved like this, i'll try transfering mine. Thanks a lot for this helpful guide.
