And are there any potential issues I should be wary of?
you should always avoid "importing" private keys generated in another wallet into a different wallet. always sweep them or simply create another set of keys for different purpose like having a hot spending wallet on your phone. use import as your last resort and only if you have no other options.
for example with bitcoin core you can be absolutely sure that your wallet (keys) is safe as it is extensively tested and reviewed by lots of experts and that is something which is not true for many mobile wallets specially those that are brand new.
