Several of the same gene symbol id for different ensembl ids in RNA-seq data

Question

[BioQueen]

Hi! I'm working with high throughput RNA-seq and in the data set I have different ensembl ids but some of the gene name ids/gene symbols are the same. How do I solve this problem, do I just keep the ensembl id for all ensembl ids, or do I have to handle that some of the ensembl ids correspond to the same gene name?

Multiple ensembl gene ID for the same gene name (Symbol), how to deal with this while differential analysis?
How to deal with the case that one gene symbol matches multiple ensembl ids?
Why am I getting different ensembl gene ids for a given gene symbol?
